NUEVO, Calif. – The Riverside County Transportation Commission (RCTC), in partnership with the County of Riverside, celebrated the groundbreaking of the Mid County Parkway Ramona Expressway Project on June 24, 2026. The milestone highlights major transportation improvements now underway to provide a vital east-west connection for Riverside County residents and improve mobility for the region’s growing communities. Construction began in early spring 2026 and is anticipated to be complete in 2028.

“Improving safety and mobility between Perris and San Jacinto has been a longstanding priority for the region. Thanks to our partnership with the County of Riverside and the State of California, we are delivering on that priority,” said RCTC Chair Raymond Gregory. “This stretch of roadway has experienced serious safety challenges, and these improvements will make travel safer for drivers, bicyclists, and wildlife.”

The project is intended to address safety concerns along an 8.6-mile stretch of Ramona Expressway between one mile east of Rider Street and Warren Road in San Jacinto. Over the next two years, construction will include the installation of a center median to provide a barrier between opposing directions of travel and upgrades for traffic signals at key intersections. As part of the project, the bridge over the San Jacinto River will be reconstructed to accommodate additional lanes and shoulders. Additional improvements, including a wildlife crossing, a buffered bike lane, and new fencing will be implemented throughout the corridor.

The $184 million project is funded through federal, state, and local sources, including more than $21 million from Measure A, Riverside County’s voter-approved transportation sales tax. Additional funding includes $34 million from state programs supporting congestion relief and local planning, $96 million through federal transportation funds, and a $1 million contribution from the County of Riverside.

Local and state officials gathered in Nuevo on Wednesday, June 24, to celebrate the partnership and this significant project milestone.
