The improvements will be in Orange County, California on State Route 133 (SR-133) from Post Mile (PM) 11.4 to PM 13.6, and on State Route 241(SR-241) from PM 24.5 to PM 35.7 in the cities of Irvine, Orange, and Orange County, Unincorporated. The proposed project build improvements would include improvements along SR-133 south of Irvine Boulevard (Blvd) Over Crossing (OC) to Junction (Jct) SR-241 and on SR-241 south of Portola Parkway (Pkwy) OC to NB off-ramp Toll Plaza. Two alternatives are being considered, The Build and No Build Alternative. The proposed improvements of the build alternative include necessary repairs on the fire damaged guardrails, drainage facilities, roadway signs, and electrical systems. Moreover, the build alternative also aims to improve the existing infrastructure by making it more resilient to extreme weather and natural disasters. The project’s proactive approach includes drainage improvements, upgrade traffic safety devices, replacement of pavement sections impacted by the culvert replacement, landscaping replacement, electrolier replacement, and conductor loop replacement.
