One side of a 1950s-era bridge over Four Mile Run will close for reconstruction beginning next week.
The west side of the Arlington Ridge Road bridge, which crosses from Arlington into Alexandria just south of S. Glebe Road, will close next Wednesday to all vehicle and sidewalk traffic. It will remain inaccessible for about 11 months while crews demolish and reconstruct the southbound side.
During that time, one lane will remain open in each direction on the east side of the bridge. The sidewalk on that side will also be open.
The Four Mile Run Trail underpass will undergo “short-term closures” during demolition, detouring via S. Lang Street and S. Glebe Road.
“Responding to the communities’ concern for connectivity and the impact to residents living in proximity, the bridge will continue to operate during construction, but with reduced lane capacity,” a project page says. “People walking or biking will continue to have access to the bridge through the duration of project construction.”
The other half of the bridge will shut down once crews finish with the west side, and the project is expected to conclude during summer 2027.
In addition to replacing a “deteriorated” roadway and underlying bridge deck, the undertaking will move some utilities underground and will replace the current 6-foot sidewalks on either side of the bridge with 10-foot paths.
The project will also involve upgrades to the intersection of Arlington Ridge Road and S. Glebe Road, plus newly redesigned railings and a facade to pair with those of the neighboring West Glebe Road bridge.
