Boundary Channel Drive Trail Connection Plans Are Much Improved

Updated plans for the Boundary Channel Interchange Improvement Project were presented at the Arlington County Transportation Commission Meeting on April 28th, 2021. The project includes building a multiuse trail connecting Long Bridge Drive near the aquatics center to the Mount Vernon Trail. The plans incorporate several improvements requested through public outreach. Major changes to the plan include:

  • Widening of the trail on the north side.
  • Moving the trail further away from the roadway.
  • Straightening the approaches where the trail crosses on and off ramps. These previously had tight 90 degree turns.
  • Installation of Rapid Flashing Beacons at ramp crossings.
Current plans for a new trail connection from Boundary Channel Drive to the Mount Vernon Trail.

Requests for Proposals for a Design-Build contract were released February 28th with an expected award this summer. Construction is expected to begin in the Spring of 2022 with completion expected in the Fall of 2023. The presentation to the Transportation Commission is in the video below.
