Document Description
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.
