The city's first traffic signal for bicycles went into operation today at the north end of the Walnut Street Bridge at Frazier Avenue.

The city transportation department said in a news release the signal uses traditional red, yellow and green indicators but they're shaped like bicycles to alert riders to follow them.

Riders who stop over a sensor at the end of the bridge will trigger a green light that will allow them to safely cross or turn, the release said.
