Car going straight on Callowhill street in far left lane collide with car in second from the left lane making a left on 4th from Callowhill.
Sending the turning car in to the brick wall. It's only a matter of time before pedestrians are killed on that corner.
This morning it happened again, this time it involved a police cruiser.
As simple fix: as cars approach the 4th street intersection: bolder lane lines.
Lastly an arrow (NO TURNS) is needed in the second to the left hand lane.
(the same problem has caused numerous accidents at 4th and Arch) same solution is needed.)
