Skanska USA Civil is the general contractor for the $107.4 million project.

Major roadway improvements will be made along the Ramona Expressway from Warren Road to about 1 mi. east of Rider Street in the county. This segment is within the Mid County Parkway, also known as the MCP, a planned 16-mi. corridor between Route 79 in the Hemet Valley and Interstate 215 in Perris.

Construction is set to take place through 2028.

The MCP Ramona Expressway experiences a high rate of vehicular collisions. To address the high priority safety and access needs in the area, RCTC has deferred final design of the MCP Segment #1, west of Ramona Expressway. Roadway improvements along Ramona Expressway will include the following:

• an additional travel lane in each direction (one to two lanes);

• a raised median;

• construction of a new bridge over the San Jacinto River;

• traffic signal upgrades; and

• construction of a wildlife crossing

These upgrades are designed to improve motorist safety, reduce travel times and expand access to jobs, education and transit.

The Ramona Expressway serves as a vital link that provides equitable access to multiple modes of travel with connections to SR-79, I-215, and transit facilities that support Metrolink's 91/Perris Valley Line and Riverside Transit Agency routes.
