Interstate 240 Oklahoma
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
The Crossroads Renewal 240 interchange project started in June 2016 upgrades the full cloverleaf between I-240 and I-35 into a multi-level exchange. The four phase project runs through 2023. 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 rebuilds the frontage road along the southwest quadrant of the exchange joining I-35 and I-240. It also permanently closed the on-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 will be completed in summer 2018. Phase 1B, planned for fiscal year 2020, 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 2 through 4 are scheduled for fiscal year 2021.

The initial section of the Interstate 240 completed was the Southwest Expressway extending west from I-35 to the U.S. 62 freeway south to Newcastle. The route was posted as U.S. 62.
Interstate 240 extended north over former I-440 along both the West Bypass and east along side U.S. 66 (Northeast Expressway) to form a three-quarter beltway around Oklahoma City.
A section of Northeast Expressway, between Eastern and Lincoln Boulevards, was the first four-lane roadway to open in Oklahoma. That roadway, opened in October 1950, was later designated as part of Interstate 440.2 I-440 formed the northern third of the Oklahoma City belt line to Interstate 35 near Lake Aluma. I-240 was designated along the southern loop, from I-40 west of Downtown Oklahoma City south and east back to I-40 beyond Tinker Air Force Base.
Approved by AASHTO on June 17, 1975, I-440 was renumbered as Interstate 240, giving the entire loop a single designation. Exit numbers assigned to the freeway initially used the mileage for I-40.
Further changes for Interstate 240 were made, with Interstate 44 overtaking both the original I-440 section, and the north-south leg of I-240 as part of its extension from the Turner Turnpike near Edmond south to Lawton and Wichita Falls, Texas. AASHTO approved the designation changes on June 28, 1982.
I-44 leading south from I-240 to the H.E. Bailey Turnpike north end at Newcastle was designated as U.S. 62 from 1965 to 1982. I-240 from U.S. 62 to U.S. 66 opened on March 23, 1976. From 1978 to 1980, U.S. 66 was detoured along Portland Avenue north to NW and NE 63rd Streets east and Kelley Avenue south while Interstate 240 was constructed.3
