SAN FRANCISCO -- A tech bus navigating one of San Francisco's steep hills in the Noe Valley neighborhood found itself stuck and blocking traffic Tuesday morning.
Arthur Patterson sent photos to the blog SFist, showing the bus wedged in the pavement and unable to move at 21st and Chattanooga streets at around 9 a.m.
The stuck bus also temporarily blocked Muni's J-Church streetcar tracks.
Muni sent out shuttle buses of their own to get their passengers around the blockage.
The stuck bus became unstuck with the help of a tow truck about 30 minutes later.
