Document Description
The California Department of Transportation (Caltrans) proposes an operational improvements project on State Route 133 (SR-133) from 0.2 miles north of Route 133/405 separation (PM 8.3) to Irvine Center Drive Overcrossing (PM M9.3) in the City of Irvine, in the County of Orange. The project proposes to construct new auxiliary lane on southbound (SB) SR-133 from NB 1-405 connector to SB 1-5 connector. This new aux lane will become the 2nd lane on NB 1-405 Connector. The number 3 lane on SB SR-133 will be extended approximately 300 feet south of San Diego Creek to match existing roadway pavement.
