Under Construction: Boundary Channel Drive at I-395 Interchange Improvements in Arlington County

Cost and schedule ►

Traffic alerts ►

Public outreach ►

Please note: The southbound I-395 ramp to westbound Boundary Channel Drive (Exit 10A) is closed until mid-2023. During that time, drivers can use the southbound I-395 Exit 9 (Clark Street) ramp to access both westbound and eastbound Boundary Channel Drive.

This project will upgrade the Boundary Channel Drive at I-395 interchange and make bicycle and pedestrian improvements in the area.

The project includes reducing underutilized roadway capacity on Boundary Channel Drive in order to construct a 12-foot-wide westbound shared-use path and an eight-foot-wide eastbound sidewalk. The half-mile shared-use path will create a new link between the Mount Vernon Trail to the Pentagon and Long Bridge Park by tying into the existing path that parallels the southbound George Washington Memorial Parkway ramp to southbound I-395.

Other project improvements include:

  • Installing roundabouts on Boundary Channel Drive just west and east of I-395
  • Reconfiguring the ramps between I-395, Boundary Channel Drive and Long Bridge Drive
  • Adding crosswalks along Boundary Channel Drive and Long Bridge Drive

Estimated Costs
Preliminary Engineering - $509,000
Right of Way Acquisition and Utility Relocation - $550,000
Construction - $18.6 million
Total - $19.6 million

This project is financed with state (including Revenue Sharing), Arlington County and Northern Virginia Transportation Authority funding.
