Glebe Road to Close Near Chain Bridge for Nine Days in 2021

N. Glebe Road is expected to close for nine straight days next year for a bridge rehabilitation project.

In a recently-posed video presentation, VDOT provided an update on its planned Pimmit Run bridge project. The presentation details the plan to replace the deteriorating bridge deck and steel supporting beams with large, prefabricated components.

Sections of the bridge deck and support beams will be constructed off-site and trucked in, then placed with a crane. That will allow crews to replace the entire top of the bridge much faster than with conventional construction techniques, which would require a sequential series of lane closures.

The downside is that the bridge — and thus N. Glebe Road, just up from Chain Bridge — will need to be closed to traffic entirely for an estimated nine days next year.

The project is set to kick off next spring and wrap up in the fall of 2021. Its projected cost of $9.5 million will come from state and federal funds.

The bridge was built in 1973, serves 13,000 vehicles per day, and is suffering from corroding concrete and steel supports. The project will replace the entire bridge deck and support beams, while also repairing the concrete bridge piers in and around Pimmit Run, near where it flows into the Potomac.

The rehabilitated bridge will have new rails and barriers, as well as a widened pedestrian path.

During the project, traffic heading to and from Chain Bridge will be detoured via McLean and N. Chain Bridge Road. A closure of N. Glebe Road just up from the bridge last week, due to water main work, resulted only in minor traffic impacts — albeit during a pandemic during which many people are working from home.

VDOT is asking for anyone with feedback on the project to email [email protected] by Aug. 7.
