RCTC, in conjunction with project partners Caltrans, the City of Perris and the Western Riverside Council of Governments, reconstructed the Route 74/Interstate 215 Interchange Project in Perris. The new interchange was designed to improve traffic flow, access to downtown Perris and connections to northbound and southbound I-215. The centerpiece of the project was the replacement of the existing two-lane bridge over the freeway with an eight-lane bridge, with two through-lanes and two left-turn lanes in both directions.

The centerpiece of the project was the replacement of the existing two-lane bridge over the freeway with an eight-lane bridge, with two through-lanes and two left-turn lanes in both directions. Other improvements included:

• Realigning freeway on-ramps and off-ramps and adding meters and carpool preference lanes to on-ramps
• Removing a five-point intersection and 12 stop signs west of the freeway and replacing these with new intersections controlled by traffic signals
• Installing new drainage systems
• Widening Redlands Avenue from 4th Street to San Jacinto Avenue
• Constructing sound walls and retaining walls
• Building an eight-foot sidewalk on the north side of the bridge
