One person was hospitalized with critical injuries Friday after a two-vehicle crash shut down a major street in San Francisco’s Richmond District, officials said.

The wreck happened about 11 a.m. on Fulton Street at 18th Avenue on the north side of Golden Gate Park, officials said.

One driver apparently suffered a medical emergency just before collision, said Lt. Jonathan Baxter, spokesman for the San Francisco Fire Department.

San Francisco police officers were investigating the circumstances of the crash.

At the scene, vintage powder-blue Volkswagen Beetle with a crumpled front end was parked in the middle of Fulton Street, but it was unclear if it had been driven by the person who was critically hurt. Parked in the opposite direction was a white Ford pickup truck also with front in damage.

Fulton Street was closed between 17th and 19th avenues as police investigated.
