The public review period runs from May 22- June 22, 2020.

Caltrans, the City of Indio, and Riverside County are considering three alternatives for the interchange, which will be presented at the meeting.

“Alternative 1” is no change to the interchange, “Alternative 2” is a tight-diamond design, and “Alternative 4” is a diverging-diamond design.

The proposed changes include redesigning existing on- and off-ramps, the I-10/Monroe Street bridge overcrossing and the Coachella Valley Stormwater Channel bridge; adding an eastbound auxiliary lane between the Monroe Street and Jackson Street interchanges; adding acceleration and deceleration lanes at the westbound Monroe Street on- and off-ramps and a deceleration lane at the eastbound Monroe Street off-ramp.
