Boundary Channel Interchange

Boundary Channel Drive Interchange

Arlington County proposes to redesign the Boundary Channel Drive Interchange with I-395 to improve traffic flow on a major traffic thoroughfare between the County and the District of Columbia. The project will construct two roundabouts at the terminus of the ramps from I-395 to Boundary Channel Drive, eliminate redundant traffic ramps to/from I-395, and remove a dangerous weave-merge improving traffic flow and safety. In addition, the project will create multi-modal connections to/from the District of Columbia that will promote alternate modes of commuting into and out of the district.

Highlights

  • Elimination of a dangerous weave merge along I-395 southbound
  • Improved pedestrian and bicycle infrastructure along Boundary Channel in anticipation of the completion of the connection to the Mount Vernon Trail via Humpback Bridge

Status/Schedule

  • The Northern Virginia Transportation Authority approved Arlington County's application for approximately $4.3 Million in July of 2013
  • Preferred alternative selected in 2016 (illustrated above)
  • Project is currently in design with construction anticipated to begin in 2020
