The TriTunnel Express is a proposed 10-12 mile tunnel system consisting of three 45-foot diameter tunnels under the Santa Ana Mountains.

This direct-route tunnel starts slightly south of Interstate 15 freeway (1-15) and Cajalco Road Exit in Riverside County. It extends through the Santa Ana Mountains under the Cleveland National Forest to the interchange of SR 241 and SR-133 in Orange County. It is the BEST alternative to the Riverside Freeway (91) congestion
