SR 120 Union Road Interchange

SR 120 Union Road Interchange introduced California’s first Diverging Diamond Interchange (DDI), improving traffic flow and safety at a key SR 120 crossing in Manteca. MVE supported the project with construction surveying and staking, including site control, pedestrian ramp surveys, and settlement monitoring. The project also incorporated a 12-foot-wide, grade-separated Class I bicycle path that eliminates bicycle and vehicle conflict points through the interchange.
