Platform Bridge
Posted October 5, 2020, by Doug Klingerman


"As of January 13, 2020, the bridge known as the Old Tocaloma/Platform Bridge, which runs parallel to Sir Francis Drake Boulevard at its intersection with Platform Bridge Road ~2 miles east of Olema, is closed to all vehicular traffic until further notice. The bridge is being closed to vehicular traffic due to structural deficiencies that make the weight of a vehicle unsafe to cross over the bridge."

Any source on pedestrian only? As of November 2016 street view, it appears to be open to traffic with a 5 ton weight limit.

I don't know why anyone would use it given there's an easier way, but it wasn't closed to traffic.
