Construction activity related to the Boundary Channel Drive at I-395 Interchange Project will close a portion of the existing unpaved social path near the Pentagon Lagoon beginning on 1/25/2023. The point of closure will be approximately 1000 feet south of where the Mt. Vernon Trail passes underneath the George Washington Memorial Parkway. Signage will be installed to alert path users of the closure. The path will remain closed for up to 6 months as the Project reconstructs the Interchange between BCD and I-395 and constructs a new paved path connecting the existing path to Boundary Channel Drive.

This project will realign the current ramps to I-395 creating two traffic circles with off road paths that connect to the path on Long Bridge, the Mount Vernon Trail and the Pentagon.

A picture of the closures, which includes closing Exit 10A is below. Boundary Channel Drive will remain open during this phase of construction.
