| 摘要： | There's no question that the 1,500-acre historic Presidio of San Francisco national park is special. The same goes for the new 14-acre site within it known as Presidio Tunnel Tops. Situated on a sloping hillside, the $118 million Presidio Tunnel Tops park, which opened to the public on July 17, offers panoramic views of familiar landmarks - the Golden Gate Bridge, Alcatraz Island, Angel Island, the San Francisco Bay, the Marin Headlands, and even the city's famous downtown skyline. The new park - part of which is atop two new highway tunnels that carry vehicles to and from the Golden Gate Bridge - will provide an unobstructed pedestrian connection between the waterfront and the Presidio for the first time in nearly 80 years. But long before the first visitors ambled through the new park's Cliff Walk pathway in July, picnicked on its expansive Central Lawn, or sent their children off to explore the Outpost's 2-acre, nature-based play areas, civil engineers had to resolve a host of complicated challenges inherent to the site. |
