UPDATE, 5:30 p.m.: All lanes reopened ahead of the afternoon commute today on state Highway 1 in San Francisco after a fallen eucalyptus tree blocked part of the roadway.

The tree came down just before 1:30 p.m. on a white Ford Escort that was headed south on Veterans Boulevard, just north of the MacArthur Tunnel in the city’s Presidio District, CHP officials said.

No one was injured. The tree was still blocking both southbound lanes as of about 2:10 p.m. and portions of the northbound lanes were blocked as well.

There was no immediate estimate for when the road would reopen.
