State Route 191 (SR 191) is a state highway in the U.S. state of California. Known also as Clark Road, it is a spur route off of State Route 70 in Butte County, providing a connection to the town of Paradise.
Construction of California State Route 191 was planned in 1962 but wasn't constructed due to U.S. Route 40 Alternate (now California State Route 70) not being moved upward due to Lake Oroville. Construction started in 1963 when U.S. Route 40 Alternate was moved.
The route was completed in 1964 and opened the same year.
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). Segments that remain unconstructed or have been relinquished to local control may be omitted. The entire route is in Butte County.
