California State Route 191
highway in California
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.
Route description
Route 191 is defined in section 491 of the California Streets and Highways Code, and that the highway is "from Route 70 near Wicks Corner to Paradise".
State Route 191 begins at State Route 70 north of Wicks Corner in Butte County. It then heads northward and intersects Durham-Pentz Road. It then ends at Pearson Road in Paradise.
SR 191 is not 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.
Construction of State Route 191 was planned in 1962 but was not 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.

Why this record matters
The subject matters to the general reference register because the source frames it as highway in California. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 14, 2026. The linked authority identifier is Q758186. Authority coordinates are 39.741, -121.608. 2 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1962, 1963 and 1964.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
