Like a bird stealing your worm, Caltrans is getting a jump on its weekend closure of 280. SF Gate reports that Caltrans and the California Highway Patrol will start barricading northbound entrances to 280 on Thursday at 2 p.m. On ramps will be closed at Alemany Boulevard, the U.S. 101 connector to 280, Indiana/25th St., and 18th St. They will remain closed through the Labor Day weekend and reopen on Tuesday at 5 a.m. Anyone coming into the city from the South Bay will will have to take 101, where they will, presumably, have an excellent view of the bumper in front of them. The southbound lanes will remain open. 

Caltrans told the Gate the early start time was necessary because they have more work to do than during the two most recent closures, both of which also happened on holiday weekends. The agency plans on replacing two bridge hinge joints, which give the elevated highway enough flexibility that it doesn’t collapse during an earthquake. As much as we all hate traffic, it’s hard to argue with the need for these safety measures, especially after that shaker we had last weekend. So leave early, and call 511 for real-time traffic updates.
