I-10 Jefferson Street Interchange

TYLin performed Construction Management and Inspection services for the I-10/Jefferson Street Interchange in the City of Indio, California.

The I-10/Jefferson Street Interchange project was the last and largest of six interchanges to be constructed along the I-10 Coachella Valley Corridor. The project replaced a modified diamond configuration that was constructed in 1958, and had geometric deficiencies and operational limitations. 

The project included constructing a 445-foot-long, 155-foot-wide, eight-lane bridge over I-10, removing two existing bridges, and constructing of new eastbound and westbound on- and off-ramps. Auxiliary lanes were added on I-10, as well as a 50-foot-tall MSE retaining wall and Type 1 retaining walls.  

TYLin oversaw extensive coordination with multiple public agencies, including the Riverside County Transportation Department (RCTD), Cities of Indio and La Quinta, California Department of Transportation, and utility companies. 


  • The project required extensive traffic control and playing a key role in public outreach programs. 
  • New structures contain various architectural treatments that complement the natural surroundings. 
  •  Scope of work included managing the services of 10 specialty subconsultants.
