Major work starts on the 25th. It is the first of five work packages and OkDOT claims this phase will be the most disruptive:

Major traffic impacts for I-44/US-75 interchange start January 25 in Tulsa
The first round of improvements to the I-44/US-75 interchange will begin Monday, Jan. 25 in Tulsa. 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.

Improvements in this project include:
Widening and reconstructing all pavements 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 Ave. over I-44, two US-75 bridges over I-44 and two US-75 bridges over Mooser Creek (located just south of I-44 junction).

Replacing and slightly reconfiguring all four cloverleaf ramps at the interchange to match geometry of the new elevation of the US-75 bridges over I-44.

Construction of some additional piers; these will be part of future work packages for the interchange.

While I-44 and US-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. There will also be ramp closures at the cloverleaf, along with full closures of Union Ave. over I-44 and on Skelly Dr. 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.

This is the first of five work packages to improve the I-44/US-75 interchange and the I-44 West End corridor between the Arkansas River and the western I-44/I-244 split in Tulsa. It will have the biggest impact to both I-44 and US-75 traffic out of all the work packages. Those plans for additional work in the corridor are still being developed at this time, and some are not yet funded or scheduled.
