The 1910 Estrella River Bridge is a truss span located in San Luis Obispo County which carried the original alignment of California State Route 41. The structure was added to the State Highway System in 1916 as Legislative Route Number 33 and was assigned to the corridor of California State Route 41 in 1934. The structure was bypassed in 1957 when the first unit of an expressway out of Paso Robles reached the Estrella River. During 2020 the 1910 Estrella River Bridge was restored and modernized by San Luis Obispo County.
