Route description

The route begins at State Route 1 with an interchange. SR 129 does not cross into Santa Clara County but the road comes within 700–900 feet of the Santa Cruz-San Clara County line. The road then heads northeast into the town of Watsonville along Riverside Road, where it intersects County Route G12. Heading eastward out of town, SR 129 roughly parallels the Pajaro River along the Santa Cruz-San Benito County line before entering San Benito County near Chittenden. Crossing the Pajaro River near River Oaks, the road runs southeast along Chittenden road to end at U.S. Route 101.

SR 129 near SR 1 is part of the National Highway System, a network of highways that are considered essential to the country's economy, defense, and mobility by the Federal Highway Administration.

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 to an overlap due to a correction or change, and T indicates postmiles classified as temporary (). Segments that remain unconstructed or have been relinquished to local control may be omitted. The numbers reset at county lines; the start and end postmiles in each county are given in the county column.
