The I-215 serves as a crucial transportation corridor for the Inland Empire, connecting cities such as Riverside, San Bernardino, Murrieta, and Moreno Valley, while facilitating the movement of commuters and goods between major freeways and economic hubs. As the region continues to grow, this vital corridor plays an essential role in reducing congestion and supporting regional development.

One significant infrastructure project that has improved travel along this corridor is the I-215/Van Buren Boulevard Interchange Project, located near the March Air Reserve Base in Moreno Valley. Completed in 2015, the project began construction in 2012 and was a collaborative effort between the Riverside County Transportation Department (RCTD), Caltrans, the March Joint Powers Authority (March JPA), and the Riverside County Transportation Commission (RCTC). The project was designed to accommodate future growth by reconfiguring the previous tight diamond interchange. The enhancements included the addition of new on-ramps, realignment and widening of Van Buren Boulevard, and replacement of existing bridge structures over the railroad and freeway. Additionally, the I-215 was widened between Cactus Avenue and Harley Knox Boulevard, with a minor realignment of the southbound lanes to improve traffic flow.

Further improvements outside the interchange included new traffic signals and streetlights, upgraded lighting at the northbound ramps, auxiliary lanes along the I-215 between Van Buren Boulevard and Cactus Avenue, and acceleration and deceleration lanes south of Van Buren Boulevard.

Visual design elements were integrated into the bridge structures, retaining walls, and surrounding landscaping to reflect the area’s military heritage. Moreover, regional access to the Riverside National Cemetery and March Air Museum was significantly enhanced as a result of the new interchange. The project team was recognized with the American Planning Association’s 2015 IES-APA Urban Design Award for their work in urban planning and design.

Funding for the project came from Measure A, a voter-approved half-cent sales tax measure aimed at transportation improvements in Riverside County, which facilitated its progression to construction. The collaboration among RCTD, Caltrans, March JPA, and RCTC ensured that the interchange meets the transportation needs of the region.
