Background: 
The rehabilitation of the northern section of the parkway was announced by the Department of the Interior on December 7, 2021. In partnership with the National Park Service, the Federal Highway Administration awarded a $161 million contract to rehabilitate this section of the George Washington Memorial Parkway. The project will improve the driving experience, safety and water drainage while retaining and reviving the historic beauty and significance of the parkway – including opening scenic views to Washington, D.C.
