Interstate 10/Monroe Street Interchange Improvement Project

Interstate 10/Monroe Street Interchange Improvement Project

The City of Indio (Responsible Agency), in cooperation with the California Department of Transportation (Lead Agency), proposes to reconstruct and widen Monroe Street at Interstate 10 (I-10) to improve the operational performance of the Monroe Street interchange. The Monroe Street interchange is on I-10 at Post Mile (PM) Revised (R) 54.7, between PM R53.9 (approximately 2 miles east of the Jefferson Street interchange) and PM R55.5 (approximately 1 mile west of the Jackson Street interchange). The project site is centrally located within the City of Indio at the crossroad of I-10, Monroe Street, and the Coachella Valley Stormwater Channel (CVSC) in Riverside County, California. The current I-10/Monroe Street interchange configuration is a diamond-type interchange, with signal control at the on- and off-ramp termini. The project proposes to reconstruct Monroe Street at the interchange, including the existing on- and off-ramps, the Monroe Street I-10 overcrossing, and the bridge over the CVSC. The project proposes to add an auxiliary lane in the eastbound direction between the Monroe Street and Jackson Street interchange, acceleration/deceleration lanes at the westbound Monroe Street on- and off-ramps, and a deceleration lane at the eastbound Monroe Street off-ramp.
