Dominion Substation Four Mile Run Trail Detour

  • On the week of June 6, Dominion Energy will close the section of Four Mile Run Trail in front of the substation at 3225 S Eads Street. The trail will be closed for approximately four months while they build a boardwalk to use as a temporary trail detour for the four year project. During the four-month construction of the boardwalk, a detour will be in place to re-route trail users along Route 1/Richmond Highway, Glebe Road, and South Eads Street. Adjustments will be made to the sidewalk on Route 1 and the traffic pattern on Glebe Road to accommodate the new traffic.

New Construction: Potomac Yard-Four Mile Run Trail Connection

  • Arlington County is set to begin construction of public improvements for the planned Short Bridge Park project. This project will help complete a crucial missing link between the Four Mile Run Trail, the upstream W&OD Trail, the downstream Mount Vernon Trail, and existing street connections along Route 1 and across the Four Mile Run pedestrian bridge. These improvements will consist of a 10-foot-wide concrete trail connecting the northbound Route 1 Trail with the Four Mile Run Trail extending east-west beneath Route 1, as well as removal of a section of sidewalk to accommodate a simpler connection to the Four Mile Run pedestrian bridge. Construction is scheduled to begin in December and will last approximately six months, provided no delays due to weather. During this time the contractor will maintain a construction entrance on Potomac Avenue, staging needed equipment and materials at Short Bridge Park, and will temporarily detour sidewalk traffic as necessary to complete the work. Work hours for the project will generally be 8 a.m. to 5 p.m., M-F.
