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

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.

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.
