CalTrans will reopen a brand-new Harrison St. offramp from the Bay Bridge to the South Beach district at 5:00 a.m. Monday morning, three and a half years after the original exit closed in 2005. For drivers new to the area, the exit is a left exit off the bridge, half a mile before the left-hand Fifth St. exit.

The new ramp is another milestone in the multi-year project to earthquake-retrofit the bridge, the biggest piece of which will replace the eastern span (the part between Yerba Buena Island and Oakland) with a new suspension structure due to open, oh, seven or eight years from now.
