Along the Felton & Pescadero Railroad, originally operated by the South Pacific Coast and later by the Southern Pacific Railroad, there were seven points where the right-of-way crossed the San Lorenzo River. San Lorenzo River Trestle #1, heading north from Felton, was just west of Ben Lomond beside the Hotel Ben Lomond and just north of the confluence of Marshall Creek and the river. At least two trestles were built on or around this location since the original narrow-gauged trestle would have been replaced in the early 1900s to support broad-gauged trains.
