Updates will be provided as more information becomes available. Crews continue to patch the roadway using cold mix asphalt. Crews also continue to remove slide material at PM 25 which has covered the northbound lane. Additionally, crews are at work to replace a guardrail at PM Signs at southbound Highway 1 at Lime Creek will alert travelers that the road is closed except for travel by locals.
The closure of Highway 1 from the southern approach in San Luis Obispo County continues to be set at the elephant seal vista area, four miles north of San Simeon. That location was selected as it provides an opportunity for large vehicles to turn around, an opportunity that is largely unavailable north of that location. Date: Tuesday, January 24, , at p.
The longstanding strategy of maintaining a catchment area protecting the highway with k-rail and a flexible rockfall fence is no longer feasible. The slide has advanced into the catchment area, over the protective k-rail and fence, and into the traveled way.
Debris slides, flowing mud, and rockfall, now travel down slope directly onto the traveled way with nothing to stop them. Movement of the slide is unpredictable; the slope continues to adjust as the slide moves, causing material to flow and rocks to roll into the remaining lane. Maintenance and contracted crews cut through the slide material along the highway, leaving a saturated soil mass that is actively pumping out water and mud onto the highway.
Caltrans directed the contractor to stop digging into the slide and to wait until access from above the slide could be accomplished to remove it safely. The headscarp of the slide is approximately feet above the highway and water is pumping from a spring into the displaced slide material between the headscarp and the highway below the slide.
The saturated and oversteepened slope is on the edge of stability and is very likely to fail catastrophically, that is, in a rapid manner, in the near future. The estimated time to reopen Highway 1 at Mill Creek is three to four weeks.
Crews cut a path through the base of the accumulated rock debris in order to gain access for equipment, which is being used to remove the slide material, and which is helping advance the work of restoring safe highway access. The failure of the rocky material could occur at any time and has been failing slowly since the pathway was cut, constantly bringing rocks and soil down to the roadway from the oversteepened temporary cut.
As of Jan. These repairs continue to bring material down which covers the entire roadbed. Weather permitting, the estimated time to reopen Highway 1, for at least limited access at Polar Star, is now set at 4 weeks due to the progress made on the slide in recent days. Anyone attempting to pass through these slide areas are advised that they are not only putting themselves at grave risk, but they are also transferring that risk to public safety and first responder teams who would have to respond to any incidents.
Caltrans is committed to providing access to the roadway as soon as road conditions permit. Updates will be provided as soon as new information becomes available. The closure of Highway 1 from the southern approach in San Luis Obispo County is located at the elephant seal vista area, four miles north of San Simeon. Residents are asked to wait at their driveways if they wish to join the convoy as it passes. Again, these convoys will take place on Tuesday Jan.
In meetings with the County Department of Emergency Management team over the last two days, Caltrans shared information regarding the closure of the Highway 1 due to slides at three locations.
This section provides information on every state numbered route that was ever defined in California. This includes the route's current definition, as well as historical information and all known names. This section provides information on the state's County Sign Route systems. These are the routes on the blue pentagon signs with numbers such as N4 or J7. This section provides the definitions of the various state highway types in California. This section provides information on the different types of Interstate highways, and gives a history in Interstate highway submissions by the state of California.
This section explains how highways are numbered and were numbered in California. It includes information on Interstate, U. This section provides a summary of how the numbers of state highways have changed. It focuses on two primary areas: the "great renumbering" in when the legislative route numbers were aligned with the signed route numbers, and how the U. Liikenne Los Angelesissa.

California's highway system is governed pursuant to Division 1 of the California Streets and Highways Code , which is one of the 29 California Codes enacted by the state legislature.
Since July 1 of , the majority of legislative route numbers , those defined in the Streets and Highways Code, match the sign route numbers.
For example, Interstate 5 is listed as "Route 5" in the code. On the other hand, some short routes are instead signed as parts of other routes — for instance, Route and Route are signed as part of the longer State Route 61 , and Route 51 is part of Interstate 80 Business. The state may relinquish segments of highways and turn them over to local control. If the relinquished segment is in the middle of the highway's route, the local jurisdiction is usually required to install and maintain signs directing drivers to the continuation of that highway; they are not generally required to do so if the relinquishment effectively truncates the highway at one end, or is done as part of the process to re-route a highway.
The state may also delete a highway completely and turn over an entire state route to local control. Business routes are not maintained by the state unless they are also assigned legislative route numbers. A route or sections of a route may also be considered unrelinquished - a new alignment has been built, or the legislative definition has changed to omit the section, but the state still owns the roadway — and are officially Route XU.
Some new alignments are considered supplemental [4] and have a suffix of S. These, and later extensions to the system, were numbered sequentially. No signs were erected for these routes. These were assigned to some of the main legislative routes in California. In , after the major expansion of the state highway system in by the California Legislature, California sign route numbers were assigned by the California Division of Highways predecessor to Caltrans.
The California sign route numbers were assigned in a geographical system, completely independent of the legislative routes.
