The project included constructing a 445-foot-long, 155-foot-wide, eight-lane bridge over I-10; removal of two existing bridges; construction of new eastbound and westbound on- and off-ramps; adding auxiliary lanes on I-10, as well as a 50-foot-tall MSE retaining wall and several Type 1 retaining walls; extensive traffic control; and public outreach. The structures contain various architectural treatments that complement the natural surroundings. The I-10/Jefferson Street Interchange project is the last and largest of six interchanges to be constructed along the I-10 Coachella Valley Corridor. The project replaces a modified diamond configuration constructed in 1958, which had geometric deficiencies and operational limitations.
