State Route 246 (SR 246) is a state highway in the U.S. state of California that runs from Lompoc east to Solvang and Santa Ynez, cutting through the Santa Ynez Valley and the Santa Barbara Wine Country. Its western terminus is along Ocean Avenue at the western city limits of Lompoc, and its eastern terminus is at State Route 154 in Santa Ynez.
Most of the road is two lanes wide, with the exception of the route through the cities of Lompoc and Buellton. This is the primary route from U.S. Route 101 to Solvang, one of the Santa Ynez Valley's biggest tourist attractions. It follows the Santa Ynez River for most of its length. The portion of the route through Solvang is called Mission Drive, while through Lompoc—including the portion where it is co-signed with State Route 1—it is called Ocean Avenue.
SR 246 begins at the western city limits of Lompoc, where it runs along Ocean Avenue to H Street, joining SR 1. The SR 246/SR 1 concurrency continues east along Ocean Avenue to the eastern edge of the city. SR 246 then splits from SR 1 and heads northeast out of Lompoc along a relatively flat two-lane road until reaching Buellton, where it widens upon its intersection with US 101. It narrows once again to two lanes through Solvang and Santa Ynez before reaching its eastern terminus at the junction with State Route 154. This is the main alternate route from Northern Santa Barbara County to the South Coast. It is also notable for passing two of Santa Barbara County's three Spanish-era missions, Santa Inés (in Solvang) and La Purísima Concepción (near Lompoc).
Part of SR 246 in Lompoc is in 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.
In 1933, this was designated as a state highway, and was numbered as Route 149 in 1935. In 1963, it was part of State Route 154. In the 1964 state highway renumbering, it was renumbered to SR 246. SR 246 used to run all the way west to Surf, but this segment along Ocean Avenue to the western city limits of Lompoc was relinquished to local control in 1984.
Except where prefixed with a letter, postmiles were measured on the road as it was in 1964, based on its original western terminus in Surf, 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). Segments that remain unconstructed or have been relinquished to local control may be omitted. The entire route is in Santa Barbara County.
