Closures this evening: On Tuesday, August 27, 2013, the westbound Fish Ranch Road on-ramp in Orinda, Bore Three and the Caldecott Lane off-ramp in Oakland will be closed, beginning at 10 PM and reopening at 4 AM on Wednesday, August 28, 2013.
In addition to the excavation of a 3,400-foot-long tunnel north of the existing three bores, the $405 million Caldecott Fourth Bore Project includes traffic improvements on the eastern and western sides of the tunnel. The tunnel is on schedule to open to traffic in late 2013.
