Mount Vernon Avenue Bridge Getting Major Makeover to Improve Safety and Access

ALEXANDRIA, VA – Good news for commuters, cyclists, and pedestrians who rely on the Mount Vernon Avenue Bridge: A long-awaited and much-needed upgrade is finally on the way. Starting in mid-August, the bridge over Four Mile Run will undergo a major $23.8 million reconstruction to improve safety, structural integrity, and accessibility for everyone who travels between Alexandria and Arlington.

The project, which is a 50/50 joint capital investment between the City of Alexandria and Arlington County, will replace deteriorating infrastructure, modernize the bridge deck, and preserve important pedestrian and trail connections.

“The bridge has served the community for decades, and this reconstruction will ensure it continues to do so—safely—for decades more,” said officials from both jurisdictions. The project comes in response to ongoing structural concerns, including the closure of the west-side sidewalk due to wear and tear.

During construction, one lane of traffic in each direction will remain open at all times, as will at least one sidewalk to maintain pedestrian access. However, drivers and trail users should expect detours, lane reductions, and weekend parking restrictions along Mount Vernon Avenue for the duration of the project, which is expected to last two years.

Phase 1 is scheduled to begin after a two-month pre-construction period, which will see traffic moved to the outer lanes while crews work on the median. Trail detours are in place on the Arlington side, while access remains open on the Alexandria side.

As part of its commitment to environmental stewardship, the City of Alexandria will oversee erosion and sediment controls along Four Mile Run and install protective fencing around trees and green spaces during the work.

“This project is not just about concrete and steel,” said one city representative. “It’s about making sure our infrastructure meets the needs of a growing, connected community—on foot, on bike, and by car.”
