Noticeable construction is scheduled to begin June 11 as crews remove guardrails, install temporary lane dividers and pave the median.
That work will require some off-peak lane closures.
Windy Run Bridge is about 2 miles south of Virginia Route 123, 7 miles south of the Capital Beltway and 1 mile north of Spout Run Parkway.
“We recommend taking public transit, using a different driving route or working from alternate locations while the bridge is under construction,” said park Superintendent Alexcy Romero.
The work that happens in June will be in preparation for impactful repairs the following month.
Starting in late July, the speed limit in the work zone will be lowered to 35 mph and the number of lanes will be reduced on and around Windy Run Bridge.
There will only be three lanes of traffic — one southbound, one northbound and another will be reversible to accommodate morning and evening rush hours.
“Please use extra care in the area,” Romero said. “Follow the posted speed limit, and watch for construction crews along the road. Let’s do our part to make sure we all get home safely at the end of the day.”
This project will extend the life of the bridge by 15 years and help address issues with recurring potholes, according to Romero.
The National Park Service also is planning for a full rehabilitation of the entire north section of the George Washington Parkway from Spout Run to Interstate 495/Capital Beltway. That project will be open for public comments for 30 days later this summer.
