More than 200 traffic signals across The City malfunctioned Tuesday, according to transportation officials.

The outages were resolved by 1:34 p.m., according to the San Francisco Municipal Transportation Agency.

Most of those blinking red traffic lights were concentrated on Third Street in the South of Market neighborhood and in the Embarcadero, according to the SFMTA. However the malfunctioning traffic signals were reported in other locations as well.

“Numerous traffic lights are malfunctioning in multiple locations throughout the city,” read an alert from the AlertSF notification system, sent to San Franciscans at 12:30 p.m. Tuesday.

The City boasts some 1,200 traffic signals, according to the SFMTA. The malfunction was caused by a “network issue,” said SFMTA Director of Transportation Ed Reiskin, at the regular meeting of the SFMTA Board of Directors on Tuesday afternoon.

“Late this morning we had a network issue that affected traffic signals,” Reiskin told the board.

“Our signal folks and IT folks were on this quickly,” he said, “certainly by the end of the meeting they’ll be restored.”

In fact, the lights were restored before the meeting ended.
