This project will improve the existing freeway interchange at Interstate 15 (I-15) and Limonite Avenue, located within the cities of Eastvale and Jurupa Valley in Riverside County. Within the project limits, I-15 currently is a six-lane, three mixed flow lanes in each direction, accessed, controlled freeway.Along I-15, improvements are proposed from approximately 0.60 miles south to 0.60 miles north of the existing Limonite Avenue overcrossing (OC) bridge. The project extends along Limonite Avenue from Hamner Avenue to Wineville Avenue. The Limonite Avenue OC bridge currently provides two traffic lanes in each direction and two left-turn lanes at the ramp intersections. This project proposes replacing the existing Limonite Avenue OC and widening the roadway from four lanes to six lanes and reconstruct the ramps to provide a partial cloverleaf (Type L-7), and constructing loop ramps in the southeast and northwest quadrants. The on and off ramp gore points will be extended providing longer acceleration and deceleration capacity.
