What's Being Done

VDOT is adding a fourth lane in both directions to a six-mile stretch of I-95, between the Fairfax County Parkway and Route 123. This will relieve chronic bottlenecking and improve traffic flow to and from the recently completed Springfield Interchange.

Lane Closures

While much construction will take place behind concrete barriers, daytime (non-rush hour) lane closures occur with occasional night work.  Northbound I-95 lane closures occur from 9:30 a.m. to 3:30 p.m. Monday through Thursday and from 9:30 a.m. to noon on Fridays. Southbound I-95 lane closures occur from 8 a.m. to 2 p.m. Monday through Thursday and from 8 a.m. to 11 a.m. on Fridays. These hours are slightly different from other projects in the region to provide as much capacity as possible for southbound I-95 traffic during the afternoon rush hour.

From late August to late October 2010, nighttime paving will close multiple lanes of I-95 south from 9 p.m. until 5 a.m. Sunday - Thursday. After 10:30 pm each night, HOV reversible lanes could be used as alternative to miss the work zone.
