A bicyclist was struck and injured at the famously troublesome San Francisco intersection of Fell Street and Masonic Avenue on Tuesday morning.

A man in his late 40s was conscious when emergency crews responded around 9 a.m. and his injuries did not appear life threatening, fire officials said.

Further details about the accident were not immediately available.

The intersection has been accident-prone for years. Cars turning left from Fell Street onto Masonic Avenue create a danger for crossing bicyclists and pedestrians. A new traffic signal system was installed in 2008 to increase safety, but some citizens later complained that motorists either ignore the system or are confused by it.
