Interstate 240 forms a southerly bypass of central Oklahoma City for I-40 west to El Reno and east to Shawnee. The freeway also provides connectivity with Interstate 44 leading southwest to Lawton and I-35 south to Dallas. I-240 also serves commuters to Tinker Air Force Base, Will Rogers World Airport (OKC) and the south suburbs including Moore.
Crossroads Renewal 240
Started in June 2016, the Crossroads Renewal 240 interchange project upgrades the cloverleaf joining I-240 and I-35 into a multi-level exchange. The four phase project runs through
2023 2026. Completed in May 2017, Phase 1 work reconstructed the Southwest Expressway east from Santa Fe Avenue (Exit 3B) to past Shields Boulevard. The $12 million phase included interim ramp changes at Shields Boulevard.
Phase 1A rebuilt the frontage road along the southwest quadrant of the exchange joining I-35 and I-240. It also permanently closed the entrance ramp to I-240 east from Shields Boulevard and the southbound off-ramp from I-35 to SE 82nd Street. Started in June 2017, the $10.6 million project was completed in Summer 2018. Phase 1B, planned for fiscal year 2021, will redesign the remaining frontage roads.
Phase 2 will construct the flyovers from I-35 north to I-240 west and from I-35 south to I-240 east. It will also replace the eastbound span for Interstate 240 over I-35. Phase 3 will complete work along Interstate 240 east between Shields Boulevard and Eastern Avenue, while Phase 4 upgrades the westbound direction along the same stretch. Phase 4 also includes work on a new bridge for I-240 over I-35. Phases 4, 2 and 3 are scheduled for fiscal year 2021, 2023 and 2025 respectively.
