State Route 131 (SR 131), named Tiburon Boulevard along its entire length, is a state highway in the U.S. state of California in Marin County. It is a short route that connects U.S. Route 101 with the town of Tiburon.

Route description

The route follows the northern and eastern shorelines of Richardson Bay, an inlet of San Francisco Bay north of Sausalito. Approximately the first half of the route is four-lane divided road, until it reaches the site of the old railroad trestle and Blackie's Pasture, after which it narrows to two lanes on Tiburon Peninsula heading into Tiburon.

Beyond its western terminus at U.S. 101, Tiburon Boulevard becomes East Blithedale Avenue, which leads into Mill Valley. Its eastern terminus is at the intersection with Main Street in Tiburon, after which the road becomes Paradise Drive, a winding route which loops around the eastern side of Tiburon Peninsula, eventually leading to Corte Madera.

History

Route 131 is part of the state highway system maintained by Caltrans because it was part of a larger plan in the 1950s to construct another bridge to San Francisco via Angel Island to complement the Golden Gate Bridge.^[2][3]

Major intersections

Except where prefixed with a letter, postmiles were measured on the road as it was in 1964, based on the alignment that existed at the time, and do not necessarily reflect current mileage. R reflects a realignment in the route since then, M indicates a second realignment, L refers an overlap due to a correction or change, and T indicates postmiles classified as temporary (for a full list of prefixes, see the list of postmile definitions).^[1] Segments that remain unconstructed or have been relinquished to local control may be omitted. The entire route is in Marin County.
