The Virginia Department of Transportation (VDOT) project on Arlington Boulevard is replacing the aging Courthouse Road bridge. This project will improve traffic flow and safety at the interchanges on Route 50/Arlington Boulevard at 10th Street and at Courthouse Road. These interchanges were constructed in the early 1950's, are tightly spaced by today's standards, with short acceleration lanes and insufficient capacity for current and future traffic volumes.
The 10th Street and Courthouse Road bridges over westbound Arlington Boulevard will be replaced, and dedicated acceleration/deceleration lanes will be added on Arlington Boulevard, separated from the main roadway. These new lanes will improve traffic flow by managing the merge of entering and exiting vehicles.
