A plan to renovate a 13-acre area that will replace the elevated Doyle Drive highway and connect the Presidio's historic core with the San Francisco Bay waterfront, known as the New Presidio Parklands Project, is also currently underway. The project is a joint operation between the Presidio Trust, the National Park Service, and the Parks Conservancy. It calls for 10 acres of landscaping that will run above road tunnels, a plaza for the Presidio Visitor Center, and a "Learning Landscape" that will incorporate the new campus for Crissy Field Center.
