I-495 North Shoulder Lane Use
|From the Express Lanes merge to George Washington Parkway in Fairfax County|
Project at a Glance
About the Project
VDOT began work on June 1, 2014 to improve travel conditions where the northbound 495 Express Lanes join the regular lanes.
The 1.5-mile project will allow traffic to travel on the left shoulder of northbound I-495 from where the 495 Express Lanes end to the George Washington Parkway. The existing shoulder will be rebuilt to accommodate traffic.
The shoulder will be open to all traffic during peak travel periods. A lane-use management system, with green arrows and red "X's", similar to the lane-control system on I-66, will alert travelers when the shoulder is available.
In addition, the project includes several safety enhancements such as upgraded concrete barriers in the median of I-495, new cameras and electronic highway signs to help with incident response and traveler information, and rehabilitating the pavement for a smoother ride.
All travelers and buses will benefit from the new capacity and improved merge. There will be no barrier separation between the shoulder lane and the regular Beltway lanes, ensuring easy access for travelers.
VDOT and its contractor are making every effort to accomplish a large portion of work during nighttime hours, when traffic is typically lighter.
In general, motorists should expect lane closures to occur on this stretch of I-495 North as follows:
Daytime Lane Closures:
- Mondays through Thursdays: From 10 a.m. to 3 p.m.
- Fridays: From 10:00 a.m. to noon
Nighttime Lane Closures:
- Mondays through Thursdays: From 9 p.m. to 5 a.m.
- Fridays: From 10 p.m. to 9 a.m. on Saturday mornings
- Saturdays: From 9:30 p.m. to 9 a.m. on Sunday mornings
- Sundays: From 8:30 p.m. to 5 a.m. on Monday mornings
Occasionally, VDOT will close all lanes on this section of I-495 North for intermittent periods during overnight hours, but will work to inform the public in advance.
