A bicyclist was hospitalized Monday after being struck by a driver making an illegal right turn at the troubled intersection of Market and Octavia streets.

A 24-year-old San Francisco woman was driving east on Market Street at 8:27 a.m. Monday when she attempted to turn right onto the Central Freeway onramp, despite posted warnings and a concrete barrier to deter motorists, police said.

The driver’s Toyota sedan struck the cyclist, a 28-year-old San Francisco woman, as she pedaled east in the Market Street bike lane.

The victim was thrown from her bike, suffering facial injuries and abrasions to her head. She was able to speak, and is expected to survive, Sgt. Lyn Tomioka said.

The driver immediately called for help and admitted to police she was making a right turn onto the freeway.

“She took complete responsibility,” Tomioka said.

The driver was not cited, but investigators may cite her later, Tomioka said.

The intersection has raised the ire of bicyclists after a string of serious injury accidents. In December 2007, The City built a barrier island to deter scofflaw motorists from making illegal right turns onto the freeway.

While the measure has helped, the heavily-traveled route remains perilous, San Francisco Bicycle Coalition program manager Andy Thornley said.

Last year, Assemblywoman Fiona Ma proposed a bill that would allow for the installation of a traffic enforcement camera to catch those making illegal right turns at the corner. The bill was shot down.

Assemblyman Tom Ammiano and Supervisor Bevan Dufty have also taken up the cause, but most efforts to make safety improvements have been thwarted due to a court injunction that prohibits such action until a thorough environmental review has been completed.

The injunction also stopped a plan to remove the bike lane.
