WASHINGTON— The National Park Service (NPS) will invest more than $5.6 million from President Biden’s Bipartisan Infrastructure Law for deferred and preventative maintenance on 20 bridges along the Baltimore-Washington and Suitland parkways, and more than 25 other places to improve roads and parking lots at national parks in eastern Washington, D.C., and Maryland. These include repairs in Anacostia Park, Kenilworth Aquatic Gardens, Oxon Hill Farm and Piscataway Park.  

Bridge and pavement preservation work will: 

  • Repair damaged concrete and stone masonry. 

  • Replace damaged bridge railings and missing signs. 

  • Clean and reseal expansion joints. 

  • Place more than 60 lane miles of new, high-visibility pavement markings on the Baltimore-Washington Parkway. 

  • Seal cracks and lay a new asphalt layer to pavement. 

  • Remove encroaching vegetation.  

“We look forward to continuing our investment and improvements to these national parks for neighbors and visitors,” Tara D. Morrison, park superintendent said. “National parks in eastern D.C. and Maryland have long provided important spaces for people to enjoy the outdoors, gather and travel across the region. This funding through the Bipartisan Infrastructure Law will enable the NPS to make strategic and significant investments to repair our critical facilities and infrastructure.” 

Beginning Feb. 12, drivers can expect construction along the Baltimore-Washington and Suitland parkways. There will be intermittent single-lane closures during non-peak hours. Drivers should proceed with caution in work zones, expect travel delays and plan alternate routes.  

Pavement work will be scheduled to avoid events including the Anacostia River Festival, the Lotus and Water Lily Festival and Independence Day festivities. The projected completion date is fall 2024. All work is weather permitting.   

None of the bridges or roadways are failing regular inspections. These preventative maintenance projects will extend the life of the roadways and bridges so drivers can continue using them without interruption.  

The Infrastructure Investment and Jobs Act, also known as the Bipartisan Infrastructure Law, is a $1 trillion investment in America’s infrastructure. The Bipartisan Infrastructure Law is the single largest investment in road and bridge repair and reconstruction since the interstate highway system was built. The law allows the NPS to make strategic and significant investments to repair critical infrastructure as well as enhance conservation and recreation opportunities.
