The SR-23 Widening and Sound Wall Project added lanes to SR-23, including sound walls, while the State Route 118 Widening Project expanded the Ronald Reagan Highway with additional lanes, bridge modifications, sound walls, landscaping, detector loops, ramp meters, and changeable message signs.
The project involved adding 16 miles of HOV lanes in both directions between Pigeon Pass and Redlands Boulevard, which included bridge demolition, construction of five overcrossings, Caltrans oversight, and stormwater management measures.
BergCM served as Prime for this $35.7 million interchange replacement project, featuring ramp widening, bridge reconstruction, traffic management, coordination with BNSF, and interaction with residents, businesses, and truck traffic.
