State Route 218 (SR 218) is a state highway in the U.S. state of California, connecting State Route 1 with State Route 68 in Monterey County. SR 218 takes an approach north of Monterey Regional Airport via the cities of Seaside and Del Rey Oaks.
The route begins at State Route 1 in Seaside as a 3 to 4-lane city street for about 3/4 mile. It then exits the city and enters Del Rey Oaks as a 2-lane highway where it shortly meets its east end at California State Route 68.
SR 218 is not part of the National Highway System,[2] a network of highways that are considered essential to the country's economy, defense, and mobility by the Federal Highway Administration.[3]
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 (for a full list of prefixes, see California postmile § Official postmile definitions).[1] Segments that remain unconstructed or have been relinquished to local control may be omitted. The entire route is in Monterey County.
