Repairs underway on GW Parkway’s Pimmit Run bridge in McLean

Work has begun on repairs to the George Washington Memorial Parkway’s bridge over Pimmit Run in McLean.

Construction crews are repairing façades of the structures that support the Pimmit Run Bridge as part of the ongoing project to rehabilitate the parkway’s northern section from the Capital Beltway (I-495) to Sprout Run Parkway in Arlington, according to the National Park Service.

Started around the beginning of the month, the bridge repairs are expected to continue “throughout the next couple of months,” the agency said in an update on Friday (Feb. 3).

The bridge’s lanes have been narrowed to provide more staging room for construction equipment, which is separated from the main road by a recently erected temporary barrier.

“Crews may not be visible to the traveling public as most of the work is under the bridge,” the NPS said.

Crews are also still working to install a temporary lane widening the parkway between I-495 and Route 123 (Chain Bridge Road). The added 10-f0ot-wide lane is necessary to give crews space to work and stage equipment, according to NPS.

Here’s more on what to expect during this stage of construction from NPS:

Activities include removing select trees in the median and at the outfalls, installing temporary drainage, and activities related to installing temporary pavement. Motorists may see crews remove select trees at the outfalls over the next couple of months. Additionally, once crews begin select tree removal at the outfalls near Route 123, activities may be visible from the surrounding neighborhoods. The rehabilitation project includes tree replacement, which will occur at the completion of the project.

Nighttime lane closure hours

• Northbound lane closures from 7:15 p.m. to 6:30 a.m.
• Southbound lane closures from 7 p.m. to 5:30 a.m.

“These lane closures are necessary to stage equipment and keep crews safe,” the park service said. “Lane closures may occur in the left or right lane with varying lengths; however, at least one lane of traffic in each direction will always remain open.”

Announced in December 2021, the $161 million project is the first major upgrade for the GW Parkway’s 7.6-mile northern stretch since it opened in 1962. Work is projected to finish in late 2025.
