U.S. Sens. Jim Webb (D-Va.) and Mark R. Warner (D-Va.) announced Wednesday that the National Park Service will invest over $27 million in 37 Virginia projects to upgrade facilities, extend hiking trails and promote energy efficiency at historic sites, according to a press release.

The Park Service is investing $750 million in nearly 800 projects across the nation to stimulate the economy through the American Recovery and Reinvestment Act.

The projects intend to meet the Recovery Act’s goals of generating the largest number of jobs in the shortest period of time, while making investments of lasting value for the American people.
