The traffic on 19th is so fast and so thick that it's like an interstate highway; and in fact, the state considers it exactly that, and claims ownership of the road. Leland Yee's attempts to make it more safey have been stymied by Caltrans foot-dragging and the Governor's veto of speeding-fine hikes. Until now! Apparently October's death was the tipping point, because Caltrans is finally getting to work on making things a little less manslaughtery.
A bunch of intersections will be getting better traffic signals and countdown timers (full list, plus more details, after the jump). And it only took seven years of negotiating, plus a lot of dead people. We're in SUCH good hands.
