ALEXANDRIA -- The speed limit on the Capital Beltway near the Woodrow Wilson Bridge soon will be adjusted periodically for overnight travelers.
Wilson Bridge project spokesman John Undeland says beginning late next month, an operator will adjust the speed limit based on sensors and cameras that monitor traffic.
The speed limit will vary from 50 to 35 miles per hour in northern Virginia between the Springfield Interchange and Telegraph Road.
Transportation officials hope that adjusting motorists' speeds will keep traffic flowing evenly, reducing the number of collisions.
Initially, variable speed limits will be used only overnight when some lanes are closed for construction. However, officials say the system eventually might be used full time.
