Route 28 widening project map

The Route 28 widening from Route 29 in Fairfax to the Prince William County line is officially underway, after officials broke ground last week on the $79.5 million, 2.3-mile long project aimed at easing congestion on the way to and from the Manassas area.

As part of the project, Fairfax County, the Northern Virginia Transportation Authority and the Virginia Department of Transportation will widen the existing four-lane stretch of 28 to six lanes, upgrade five traffic signals along the route and install new shared use paths for bicyclists and pedestrians on both sides of the roadway.

To fund the project, the state contributed over $33 million between VDOT revenue sharing funds and Virginia Smart Scale, the NVTA chipped in $26 million and both the county and federal government paid about $10 million each. The NVTA contribution brings the authority’s spending on the Route 28 corridor to over $350 million.

In May, Manassas and NVTA officials broke ground on a $20.2 million project to widen the stretch of Route 28 between Godwin Drive to the Prince William County line from four lanes to six and add shared use paths.

At the Fairfax County groundbreaking on Friday, Loudoun County Board of Supervisors and NVTA Chair Phyllis Randall claimed that the project would ultimately lower travel times.

“The Route 28 widening project will reduce congestion as well as improve travel reliability on the high-volume Route 28 Corridor impacting the counties of Fairfax, Loudoun and Prince William, and the Cities of Manassas and Manassas Park,” Randall said. “The project will result in vastly improved commutes to major commercial and employment centers, including the nearby Dulles Airport.”

The widening plan won approval from the Fairfax County Board of Supervisors in 2014. In Prince William County, details are still being hammered out on a Route 28 bypass that Prince William supervisors approved last year. That plan would add a new four-lane road extending Godwin Drive from the Manassas city limits to Fairfax County.

The project’s environmental review found that seven wetlands and five waterways were within the widening’s right-of-way and in areas proposed for storm water basins. To try to mitigate the project’s impact, stakeholders will purchase credits from a wetlands bank and erosion and sedimentation measures will be implemented during construction, according to Fairfax County.

Del. Dancia Roem (D-13th), who ran her first campaign for the House of Delegates on addressing Route 28’s congestion, said the impacts of the Fairfax project would be felt region-wide.

“It’s so important that we look at transportation regionally,” she said. “What helps one of us can really pay big benefits to all of us when we put all the pieces together.”

Construction is expected to take about two years, with the county saying night work is likely. Contractors are required to maintain pedestrian and vehicular traffic, as well as keep all lanes available during peak travel hours.

So this was approved back in 2014, things sure move slowly around here. I guess Danica can take credit for it when it is done so that is good. They could improve traffic right now on weekends if they would fix the Braddock road signal and give 28 a lot more time than they currently do. Specifically on weekends, the amount of traffic that is there while the light changes for 5 cars to go through on each side of Braddock is ridiculous. It will be nice not having people speed through that 3rd lane to sneak infront of cars where it changes to 2 lanes after the light though. I had no idea wetland credits existed but whatever can be done to make liberals feel better about themselves is great!

Until the Route 28 corridor includes a dedicated transitway and/or managed travel lanes to incentivize travel in multi-occupant vehicles, no feasible amount of roadway widening is likely to have a lasting effect on reducing traffic congestion.

"In Prince William County, details are still being hammered out on a Route 28 bypass that Prince William supervisors approved last year."

So far, the PW BOCS has only approved moving forward with the preliminary engineering and environmental permitting phase of the Bypass project. The BOCS will not approve actually building that Bypass until the preliminary engineering and permitting phase is completed.

So, when are they going to widen 28 in Manassas/PWC? They’ve widened I-66 several times but it never changes anything. More and more far-flung developments are built which add to the already congested roads. When everyone gets to I-66, it’s still going to be the nightmare that it is.
