Dominating the nearby skyline is a maze of freeway ramps connecting Highways 101, 280 and 680. Part of this interchange was built in the 70's. Unfortunately, that's where construction stopped. Governor Jerry Brown (yes, THAT Jerry Brown) took office and stopped funding for the interchange, leaving 3 partial ramps sitting unconnected to anything, coming from and going to nowhere. Naturally, residents began to wonder if the interchange would ever be finished. In January, 1976, a 1960 Chevy Impala appeared overnight on the topmost unfinished ramp. There's a picture in the image gallery. The story can be read here: http://www.mercurynews.com/scott-herhold/ci_24322997/herhold-story-behind-joe-collas-famous-1976-highway. This stunt embarrassed Governor Brown and spurred the eventual completion of the interchange. Click the image gallery to see the whole background picture. You're looking south on 101, notice the Story Rd sign near the middle. The cache location is near the top of the picture. It's accessible from outside the park. The cache contains a log sheet only, please bring a writing utensil.
On January 8, 2016, this interchange was officially named the Joe Colla Interchange. http://www.mercurynews.com/bay-area-news/ci_29360940/infamous-monument-nowhere-freeway-interchange-finally-named-after
