Variable Speed Limit Technology Debuts Tonight Temporary Overnight I-95/I-495 Capital Beltway Closure

Replacement of Aerial Power Lines Between Telegraph Road and the Eisenhower Connector on Wednesday, July 30

The first deployment of the recently announced Variable Speed Limit (VSL) will take place at approximately midnight tonight (July 30/31) as all lanes on both the Beltway’s Inner and Outer Loops (I-95 North and South) will be stopped for approximately 15 minutes between the Telegraph Road Interchange and the Eisenhower Connector to enable utility crews to replace power lines across the highway.

Upon detecting slowing and stopped traffic, the VSL system will lower speed limits approaching the area, reducing the likelihood of motorists having to make high-speed stops. When the power-line operation is completed, all lanes will re-open and speed limits will revert to normal once traffic backups have fully cleared.

Motorists should be aware of varying speed limits along the seven-mile portion of I-95 between the Springfield Interchange and Maryland side of the Wilson Bridge.  In addition, motorists should remember this is an active construction zone subject to additional enforcement by state and local police.

The VSL system also offers current delay-time estimates on highway signs, which are strategically placed along the I-95 corridor to enable motorists to choose a different route before they encounter congestion.  In advance of travel, motorists can also “Stay in the Know” by visiting www.wilsonbridge.com.  The website details real-time travel speeds via a color-coded map (green/yellow/red indicating highway speeds), estimated delay times and additional information to help inform decisions about travel time, route and mode.

In the event of inclement weather or the overnight work on Wednesday is not completed, the work may resume and result in additional temporary traffic stoppages the next night, Thursday, July 31 beginning at about 11:59 p.m.
