I-35/I-240 Crossroads interchange reconstruction
coming soon to south Oklahoma City

Reconstruction of the I-35/I-240 Crossroads will create a multi-level interchange with dedicated interstate ramps and improve city street access with added ramps, turnaround lanes and service roads.

Improved Traffic Safety and Efficiency

  • The new interchange will address congestion and safety issues by providing new ramps and increased merging distance to accommodate current and future traffic.

Preserved and Enhanced Business Access

  • While interstate access for businesses will change, ODOT has worked with the business community and City of Oklahoma City to design additional features to help traffic get to and from south Oklahoma City businesses, including:
    • Added I-240 on- and off-ramps to make Santa Fe Ave. a full interchange
    • Additional exit lanes from eastbound I-240 to Eastern Ave.
    • Two-way service roads between Eastern Ave. and Plaza Mayor
    • Improved local roads through Plaza Mayor that connect to service roads
    • Protected turnaround lane at S.E. 59th St. for traffic exiting from northbound I-35

Construction Timeline

  • A demolition contractor is currently clearing the right-of-way on S.E. 74th St. at the southwest corner of the interchange.
  • The first phase — reconstruction of I-240 lanes and ramps at Santa Fe Ave. — was awarded in February to Allen Contracting Inc. and Shell Construction Inc. for $12 million plus incentives for early completion.
  • Subsequent construction phases scheduled in ODOT’s Eight-Year Construction Work Plan for Federal Fiscal Years 2018, 2020 and 2021.
