Noise Barrier Votes Due July 15, 2021

The Fairfax County Department of Transportation mailed ballots to affected homeowners and tenants on June 24, 2021, asking for feedback on four proposed noise barriers. Please respond to all questions on Page 1 of the survey, then complete and sign Page 2 and return the ballot to FCDOT in the postage-paid envelope.

Your vote - along with your neighbors who are affected - is important. Thank you for your feedback!

Construction Updates - April/May 2021

In May 2021, the Route 28 Widening Project moved into its next phase, with night work and single lane closures affecting the entire length of the project. Shirley Construction Company (SCC) began mill and overlay of the entire roadway on the evening of Sunday, May 2:

  • Night work will be performed with temporary single lane closures under previously dictated lane closure restrictions and in accordance with the Virginia Work Area Protection Manual.
  • No detours are proposed for this stage.
  • No land disturbance or earthwork activities will occur.
  • This work will continue for two to four weeks.

On completion of overlay, SCC will provide pavement striping and signing, generally as noted on the 90% Plans; then shift traffic and Install barriers as shown on the 90% plans. This will enable work to begin on new roadway construction as soon as final plans are approved, with minimal impact to traffic flow during peak commuting periods.

Providing this early mill and overlay advances the initial paving operations from the original schedule of Spring 2022. The advanced paving work will repair any existing potholes, reduces the possibility of further deteriorated asphalt, and seal the joint between the recently installed temporary shoulder pavement and existing pavement. 

The first stage of construction, recently completed, included paving and strengthening portions of the existing shoulders along the entire length of the project, specifically:

  • In the southern portion of the project, between the bridge over Bull Run and the intersection of Route 28 and Old Mill Road/Green Trails Boulevard, work was completed along the outside (right) shoulder in the southbound direction and along the median (left) shoulder in the northbound direction.
  • In the northern portion of the project, between the intersection of Route 28 and Old Mill Road/Green Trails Boulevard and the interchange at Route 29, work will be completed on the outside (right) in both the southbound and northbound directions.

All work is weather dependent and will be rescheduled if inclement conditions occur.

Prince William Bypass Information

Prince William County hosted a virtual information session on Monday, Dec. 7, 2020, to inform residents of both counties about the Route 28 Bypass Project, including proposed concepts for the Route 28 Bypass connection and tie-in point to existing Route 28 in Fairfax County. Details and meeting recording will be available at

Project Background

Route 28 serves residential and business destinations from Remington in Fauquier County to Route 7 in Loudoun County, connecting Route 29, Route 234, I-66, Route 50, Dulles International Airport and Route 267 in between. The corridor has experienced increased congestion for many years, particularly in Prince William and Fairfax Counties south of I-66. To address this congestion, the Fairfax County Department of Transportation (FCDOT) proposes widening Route 28 for a distance of approximately 2.3 miles from the existing bridge over Bull Run to the interchange at Route 29. The project includes:

  • widening the existing four lane roadway to six lanes;
  • adding additional lanes on side streets to improve intersections;
  • upgrading existing traffic signals;
  • removing selected unsignalized median crossovers (breaks);
  • improving bicycle and pedestrian connections and crossings, including new 10' shared-use path on both sides of Route 28; and
  • installing Stormwater management facilities as required to meet State and County criteria.

The project was endorsed by the Fairfax County Board of Supervisors as part of the County’s Transportation Priorities Plan (TPP) on January 28, 2014 (Project ID#62).

Fairfax County and the D-B contractor will coordinate with property owners well in advance of construction. Work hours are set by VDOT and Fairfax County. Night work is likely. The D-B contractor will be required to maintain pedestrian and vehicular traffic and signals during construction. No lane closures will be allowed during peak travel hours.

Design-Build Contract

Design-Build Contract Awarded

The Virginia Department of Transportation (VDOT) authorized the award of the Route 28 Widening Project contract on May 12, 2020, to Shirley Contracting Company, LLC, based on their bid of $56,882,900. Fairfax County approved the award of the contract on May 22, 2020.

Design-Build Information

Statements of Qualifications for the RT 28 Design-Build project were received from the following firms on May 24, 2019. Technical proposals were received from short listed firms on March 6, 2020. Price proposals were received from the short listed firms on March 27, 2020.







FCDOT will use the Design-Build (D-B) procurement method to deliver the project. D-B allows for more rapid implementation of projects by combining and overlapping the design, right-of-way, utility relocation and construction phases.


How should bicyclists and pedestrians share the lane?

Bicyclists, joggers and walkers should share the closed space just like they would on a shared use path, with bikes yielding to pedestrians.

Where is the lane closure?

The northbound right lane of Tysons Boulevard connecting Westbranch Drive to the pedestrian entrance of Lillian Court at Tysons II (right before International Drive) will be closed for motor vehicle traffic and dedicated to pedestrians and bicyclists.

Tysons Boulevard closure pictures

Interacting with Motor Vehicles

When a car needs to cross the closed lane to make a turn, vehicles have the right of way, however, all users should slow down, establish eye contact and proceed with caution.

Yielding to vehicles at Park Run Road

Bicyclists and pedestrians should yield to turning vehicles when approaching Park Run Drive.

Why was Tysons Boulevard selected?

Tysons Boulevard serves a high population of residents and commuters in Fairfax County; and with only one cross-street (Park Run Drive) and no commercial or residential driveways. Even though there is a sidewalk along this stretch of road, this temporary closure will provide people with a safer option, and more space for outdoor recreation while maintaining social distancing practices during the ongoing COVID-19 pandemic.

How will this closure look?

The right, northbound lane of Tysons Boulevard will be closed mainly with concrete barriers, but also barrels and signs to protect pedestrians and bicyclists.

Tysons Boulevard Closure Barriers

Are there any other streets under consideration for this type of closure?

Tysons Boulevard is the only street being closed in Fairfax County at this time. The data collected as part of this pilot project will help FCDOT assess future street opportunities.

Prince William County Bypass

December 2020 Update

Prince William County hosted a virtual information session on Monday, Dec. 7, 2020, at 7 p.m., to inform residents of both counties about the Route 28 Bypass Project, including proposed concepts for the Route 28 Bypass connection and tie-in point to existing Route 28 in Fairfax County. Details and meeting recording will be available at


Background Information



Prince William County (PWC), the City of Manassas, and the City of Manassas Park, in cooperation with VDOT, are presently preparing an Environmental Assessment (EA) to evaluate the potential social, economic, and environmental effects associated with proposed improvements in the Route 28 corridor between Sudley Road in Prince William County and Compton Road in Fairfax County. Information on this study is available at

The EA will evaluate three alternatives developed in the December 2017 Route 28 Corridor Feasibility Study.  Limited funding is available for this project and no date has been proposed for construction[MWT2]. No major capacity improvements to Route 28 south of the Bull Run bridge are expected to be complete before 2025.

FCDOT’s Route 28 widening project will not preclude the construction of any of the alternatives in the Prince William County study. FCDOT will continue to coordinate with Prince William County as both projects progress.

Right of Way Requirements

Since the proposed widening takes advantage of the wider right-of-way available on the northbound side of the roadway, and the southbound centerline is proposed to be shifted approximately 5’ towards the median, right-of-way requirements for the roadway widening are minimized. Right-of-way required for the road widening itself are anticipated to be partial property takes of five to twenty feet in width, abutting the existing right-of-way on Route 28 and intersecting streets. Additional easements may be required for utility relocation, particularly along the southbound side between New Braddock Road and the bridge over Bull Run, and for any potential sound barrier walls that may be needed based upon the final Noise Analysis, and VDOT noise abatement policy.  

Storm water management (SWM) for the project will require acquisition of several larger parcels (which may include full takes) outside the existing right-of-way. The extent of the land rights required will be contingent upon the storm water management criteria that will be applicable to the project and the final storm water management design. FCDOT will require the Design Builder to prepare a design and acquire adequate right-of-way for storm water management facilities to serve the ultimate 8-lane section.  

If funding is available, the realignment of the Compton/Ordway/Old Centreville Road intersection may require partial or full takes of several adjacent properties, depending on the final design. 

With the exception of the land rights required for storm water management facilities, the ultimate eight-lane design can be designed and constructed without significant additional right-of-way requirements beyond the initial 6-lane section. The 6-lane widening project will acquire adequate right-of-way for the widening of the ultimate 8-lane design even though the design will be for 6-lanes in the interim. 

Based on the current design, FCDOT does not anticipate the project will require any relocations or displacements of residents or businesses.

Land Acquisition Agents from the Design Build Team will contact property owners to negotiate fair compensation for land rights required to construct the project. Land acquisition must be completed in accordance with federal, state and local laws, regulations and procedures.


FCDOT has delineated utilities within the project site and excavated 76 test holes at locations where potential utility conflicts may exist. FCDOT held a Utility Field Inspection (UFI) in August 2017 with affected utilities. Additionally, using recent 30% design plans, FCDOT will be conducting more detailed UFI meetings with each individual utility company in February and March 2019.

Utilities with facilities in the project area include:

  • Colonial Gas Pipeline (crossing Rt. 28 just south of New Braddock Road)
  • Columbia Gas Pipeline (crossing Rt. 28 just south of Old Mill Road/ Green Trails Boulevard)
  • Fairfax Water mains (up to 42 inches in diameter)
  • Upper Occoquan Sewage Authority (UOSA) and Fairfax County sanitary sewers and force mains
  • Virginia Power and NOVEC overhead and underground electric distribution and transmission lines
  • Underground and overhead telecom facilities
  • Verizon overhead and underground facilities

FCDOT anticipates the project will require utility relocations similar in scope to other projects in Fairfax County of the same size. To date FCDOT has not found any utility conflicts that would cause significant cost or delay to the project.

Environmental Studies

FCDOT is preparing a Categorical Exclusion (CE) level evaluation to determine the level of environmental impacts, determine the types of permits and approvals required, and undertake coordination with appropriate environmental resource agencies and permitting agencies.

This work included field studies for archaeological, historic standing structures, and other historic resources (i.e. battlefields), noise and air quality, and wetlands and waterbodies; and evaluations of socioeconomics (including Environmental Justice), Section 4 (f) and Section 6 (f), natural resources including protected species, agricultural/open space, hazardous materials, and cumulative and indirect effects. The work is being performed in accordance with Federal and State environmental regulations pursuant to the National Environmental Protection Act (NEPA). The Final CE was submitted for VDOT and FHWA review in late February and will be posted to the website upon final FHWA approval.   

The evaluation includes the areas within and adjacent to the existing VDOT right-of-way that may be affected by the roadway widening; and sites that have been identified as potential storm water management (SWM) facilities.  

To date, the study has found no areas of cultural or historical significance within or immediately adjacent to the existing VDOT right-of-way. Six wetlands and five Waters of the U.S. have been identified within the project corridor and candidate SWM sites.  FCDOT anticipates the maximum impact on wetlands will be approximately 0.8 acres; and the maximum impact on Waters of the United States will be about 2,500 Linear feet. FCDOT anticipates any such impacts will be mitigated by the purchase of stream and wetland credits in accordance with state and federal regulations.  

The 30% preliminary plans show the delineated wetlands and the potential noise wall locations. These plans are preliminary and subject to change based on final approval of the CE.

Environmental Impact Analysis and Studies


FCDOT conducted preliminary noise analysis per VDOT Noise Policy to determine where project noise levels are projected to exceed established criteria. FCDOT is required to propose noise mitigation. Ten sound barriers were evaluated based on the criteria of feasibility and reasonableness.

  • Acoustically effective by reducing levels at impacted receptors by at least five   decibels
  • Possible to design and construct the barrier
  • Face of barrier cannot be larger than 1,600 square feet per benefited receptor
  • At least one receptor achieves a seven decibel reduction

Two barriers were found to meet these criteria and will undergo
further evaluation by the D-B contractor (including effectiveness, exact location, length, height) during final design:

  • Barrier D1 – East side of Route 28 between New Braddock Road and Darkwood Drive
  • Barrier I – West side of Route 28 between Compton Road and Old Mill Road

Sound Barriers will be constructed only if a majority of the people who are directly benefitted vote in favor of the implementation.

Geotechnical Investigations

A Geotechnical Investigation to support the Preliminary Design  has been completed. The  study includes  a Geotechnical Design Report (GDR) consisting of soil borings and pavement cores equivalent to 50% of the requirements by the VDOT Manual of Instructions (MOI). The GDR provides boring logs for roadway pavement, retaining walls, stormwater management facilities, and large drainage pipes/culverts. The GDR also provides the existing pavement core information as well as a preliminary pavement design.

VDOT approved the final report in March 2019.

Alternative Delivery Methods and Schedule Comparison

In recent years, VDOT has employed alternative delivery methods such as Design-Build (DB) to deliver projects on an accelerated schedule. Fairfax County has endorsed the use of the Design-Build method of delivery and has used it on a number of other projects. FCDOT believes that the DB method is a reasonable alternative to consider for this project. FCDOT developed concept schedules for project delivery using both the Design-Bid-Build (DBB) method and the Design-Build Method. Using DB delivery it is estimated that the project could be completed approximately 24-28 months ahead of the standard DBB method.

VDOT’s Transform 66 Outside the Beltway project will reconstruct I-66 to provide two High-Occupancy-Toll (HOT) express lanes and three general purpose lanes in each direction, between Gainesville and the Beltway. Project completion is currently scheduled for Fall 2023. Using the Design-Build method of delivery would enable the Route 28 project to be substantially complete at approximately the same time that the I-66 project improvements become operational.

While FCDOT developed traffic models and cost estimates for the 6, 7, 8, and hybrid 6-7-8 lane concepts, FCDOT assumed that the project schedules for design and construction would be similar regardless of which widening concept was selected, with only minor changes to design and construction time frames. Time frames for completion and estimated costs for utility relocation and right-of-way acquisition for each concept were also assumed to be similar for each widening concept in order to provide comparable estimates.

The Design-Build contract procurement method for this project satisfies the following needs:

  • Maximize Use of Available Funding – Existing Federal Demonstration Funds have been appropriated to the project, which have an obligation deadline of September 30, 2019. FCDOT does not believe it can obligate these funds by the deadline utilizing the standard design-bid-build delivery method and therefore these funds would be in jeopardy. In addition, Design-Build will allow for VDOT approved Smart Scale funding to be quickly applied toward mitigating current traffic operation deficiencies.
  • Benefit to the Traveling Public – Traffic congestion along this portion of the corridor continues to increase. Political and public concern over the congestion and travel time delays continues to escalate with increasing calls for a solution as soon as possible.
  • Safety and Operational Improvements – As noted in the VDOT “Route 28 Corridor Safety & Operations Study” of 2015, the segment of Route 28 between Liberia Avenue in the City of Manassas, and I-66 has an accident/crash rate of almost double the statewide and NOVA Districtwide averages for urban primary roadways. The accelerated schedule using the Design-Build contracting method will alleviate the safety concerns and make operational improvements sooner than under a conventional Design-Bid-Build method.
  • Expedited Schedule – The Design-Build contracting method will allow for concurrent activities in the design, right-of-way and construction phases and will allow FCDOT to complete the project approximately two+ years sooner than using the traditional Design-Bid-Build method.

FCDOT prepared estimated total project costs using VDOT’s PCES system and information developed during concept design for each design under consideration. For Design-Build project delivery, the PCES system estimates were developed and then imported into the VDOT Design-Build Cost Finance Summary Worksheet. Costs include, but are not limited to; design, construction, anticipated utility relocations, right-of-way, environmental mitigation requirements, construction engineering and inspection, and VDOT oversight. Estimates were developed for Design- Bid-Build delivery for all concept designs. Design-Build estimates were developed for the 7-lane, 8-lane and hybrid 6-7-8 lanes designs.

Estimated Project Costs - Route 28 Widening (2018 Estimate)


Current Cost of Route 28 Widening Project is $86,748,000. Sources of funding include:

  • Northern Virginia Transportation Authority (NVTA) Regional Funds - $26,000,000
  • State Revenue Sharing Funds - $10,000,000
  • SmartScale Funds - $23,422,583
  • Federal Demonstration Funds - $9,407,418
  • Local Funds - $17,918,629
  • Total Funding to Date = $86,748,000

During the second round of SmartScale project selection, the amount of SmartScale funds received was $32,830,000. The initial SmartScale funding award included the repurposing of $9,407,418 in Federal Demonstration funds. These funds have an obligation deadline of September 30, 2019.

Under a Design-Bid-Build procurement schedule, FCDOT would not be able to satisfy this obligation deadline since the construction advertisement date would be approximately October 2022. However, per discussions with VDOT, the obligation deadline for these funds would be met if FCDOT utilized the Design-Build project delivery method since funds for Design-Build projects are considered to be obligated for construction once the Request for Proposals (RFP) is advertised.

A Design-Build RFP could be advertised in late Spring 2019 which will be well in advance of the September 30, 2019 obligation deadline.

FCDOT anticipates advertisement of a Design-Build RFP in the  Summer of 2019.
