Virginia transportation officials will deploy the variable speed limit technology for the first time on I-95.
About midnight Wednesday, all lanes on both the Beltway's inner and outer loops will be stopped for about 15 minutes. Utility crews will replace power lines across the highway between the Telegraph Road Interchange and the Eisenhower Connector.
Virginia transportation officials hope the variable speed limit, which went into effect Monday, will help avoid the funnel effect that occurs when lanes are closed for construction.
When it detects slowing and stopped traffic, the system will lower speed limits approaching the area.
