The Riverside County Transportation Commission, in partnership with, the County of Riverside and the cities of San Jacinto and Hemet, proposes to build a new 12-mile county expressway from south of Domenigoni Parkway north to Gilman Springs Road with two lanes in each direction. The new expressway is designed to improve safety and connectivity for the growing communities of Winchester, Hemet, San Jacinto, and surrounding areas in Riverside County.  

First conceptualized as a state route, the project was later converted to a county facility. The project will be renamed since it will not be part of the state highway system. The project is segmented into three buildable segments that will be constructed in phases and features a dedicated transportation corridor and multipurpose trail. The three segments include: 

• Segment 1 – Sanderson to Florida
• Segment 2 – Florida to Simpson
• Segment 3 – Simpson to Newport 

Design enhancements will also be considered to bolster the project’s appeal for state and federal grants – these enhancements may include multimodal features like bus rapid transit.
