MUTCD/California/C

Series C of the CA MUTCD is for temporary traffic control signs. The following tables display only the signs specific to the CA MUTCD in California; consult MUTCD/CW for warning signs in construction zones and MUTCD/G for work zone signs in the national standard.

In general, OpenStreetMap only maps long-term closures and construction sites. For routing purposes, short-term construction is more reliably and efficiently tracked in incident management systems along with real-time traffic congestion data.
