This the tunnel that connects
Cordonices Park and the Berkeley Rose Garden, far side. When I was a kid, the tunnel covered with graffiti and smelled of urine (it has been cleaned up, along with the rest of the park); I found the passage a bit menacing - it has appeared in a dream or two in middle life.
Some Berkeley histrory, from the Berkeley Gazette, September 27, 1933 (and the Web), states: " A pedestrian tunnel runs under Euclid, connecting the Rose Garden with Codornices Park. In this section, from 1912 to 1928, before the Rose Garden was established, a 275-foot-long wooden streetcar and road trestle spanned Codornices Creek along Euclid. In 1928, the trestle was filled in, a culvert laid through it for the creek, and the pedestrian tunnel constructed."
