"When they come to the Presidio Tunnel Tops," said Chris Lehnertz, President of the Golden Gate National Parks Conservancy, "they’re just going to see the grand connection that all of this makes for park lands."

The new park, connecting the historic Presidio parade ground to lower Crissy Field, owes its existence to the demise of the old Doyle Drive, which was torn down to make way for the sleek Presidio Parkway which opened in 2015. Since then, work crews have transformed the top of the parkway's twin tunnels into a sweeping park for the first time in its history.
