Responding to appeals by local merchants and the West Berkeley Association of Industrial Companies, as reported in the Daily Planet in early July, the city’s Public Works Department and its Office of Transportation have implemented changes in striping, signage and signalization at Ninth Street and Ashby Avenue and at Seventh and Murray streets. City staff have reinstated the “Keep Clear” sign that was formerly painted on Seventh just west of Murray. At Ashby and Ninth they’ve restriped the westbound lanes and removed the left turn prohibition sign. According to traffic engineer Hamid Mostowfi, the signal at Ashby and Ninth will be turned on by Sept. 3. This will all come as a surprise to the San Francisco Chronicle, which reported on Thursday that the work had not yet begun.
