'Massive' work on I-44, U.S. 75 in west Tulsa starts today

A "massive" $90 million project on Interstate 44 and U.S. 75 in west Tulsa will begin Monday.

Update (8:45 a.m.): Crews early Monday are working on setting up signs and traffic controls in the corridors leading into the work zone, ODOT says. They will be closing ramps and narrowing lanes later Monday once those are in place, according to spokeswoman Kenna Mitchell.

A “massive” $90 million project on Interstate 44 and U.S. 75 in west Tulsa will begin Monday.

The project will include:

  • Widening and reconstructing all pavement on I-44 from four lanes to six between the west side of the Arkansas River bridge and Union Avenue.
  • Replacing five bridges; one at Union Avenue over I-44, two U.S. 75 bridges over I-44 and two U.S. 75 bridges over Mooser Creek (located just south of I-44/U.S. 75 junction).
  • Replacing and slightly reconfiguring all four cloverleaf ramps at the interchange to match geometry of the new elevation of the U.S. 75 bridges over I-44.
  • Construction of some additional piers; these will be part of future projects for the interchange.

During the first few months, I-44 will be narrowed to one lane in each direction and northbound U.S. 75 will be narrowed to one lane at the I-44/U.S. 75 interchange, Oklahoma Department of Transportation spokeswoman Kenna Mitchell said.

“The first couple of months are going to be a huge traffic tie up at the interchange,” she said.

Completion of the bridge replacements, ramp realignments and highway widening is scheduled for early 2023, weather permitting.

“This massive $90 million project will greatly impact traffic in the west side of the city over the next two years, and drivers are urged to plan ahead for significant delays to commutes and travel in this area,” ODOT said in a statement.

“While I-44 and U.S. 75 will remain open during this project, there will be times that lanes will be narrowed and the corridors may only have one lane open to traffic,” ODOT said.

“There will also be ramp closures at the cloverleaf, along with full closures of Union Avenue over I-44 and on Skelly Drive at times.

“Traffic will be slow in all areas of the work zone and drivers are urged to set aside distractions and give their full attention to the road. Alternate routes such as I-244 should be considered, especially during peak travel times,” ODOT said.

The project is the largest in Tulsa’s history in terms of cost, Mitchell has said.

The work is the first of five “packages” to improve the I-44/U.S. 75 interchange and the I-44 west end corridor between the Arkansas River and the western I-44/I-244 split.

The project starting Monday will have the biggest impact to both I-44 and U.S. 75 traffic out of all the work packages, ODOT said.

Plans for additional work in the corridor are still being developed, and some are not yet funded or scheduled.

Future lane and ramp closures for the project will be announced as they are scheduled in the Traffic Advisories section of

I-44 between the I-244 western split and the Arkansas River in Tulsa is the oldest remaining section of interstate on the ODOT system.

Built in the early 1950s, the corridor predates the creation of the interstate system.

In 2018, ODOT was awarded a $45 million Infrastructure for Rebuilding America (INFRA) grant towards improvements in the corridor.

While the INFRA grant doesn’t address all needs in the corridor, “it is a tremendous first step to address several functionally obsolete and at-risk bridges, and to widen the I-44 segment immediately west of the Arkansas River,” ODOT said.

An average of 50,300 and 86,700 vehicles per day travel on I-44 between Union Avenue and the Arkansas River bridge, according to 2018 ODOT traffic counts, the most recent available.

An average of 57,300 to 69,200 vehicles per day travel on U.S. 75 near the I-44 interchange, according to ODOT.

Total cost for all improvements in the corridor is expected to be $350 million to $400 million over the next several years, officials said at a public open house on highway plans for west Tulsa in February 2020.

Mitchell at that meeting compared the west Tulsa I-44 improvements’ cost to those east on I-44 several years ago between Riverside Drive and Yale Avenue, which she said was about $380 million.
