I-235/US-77 and I-44
I-235 narrows to one lane each way
between N. 36th St. and I-44 on March 17
Northbound and southbound I-235 will be narrowed to one lane in each direction between N. 36th St. and I-44 from 6 a.m. to 6 p.m. Saturday, March 17, for preliminary work to the old BNSF railroad bridge over the interstate ahead of its removal. This work is related to the upcoming full weekend closure of I-235 in early April to fully remove the old railroad bridge.
Motorists are advised to expect delays this weekend and to stay Off Broadway by using alternate routes such as I-35, SH-74/Lake Hefner Parkway, I-44, I-40 and Lincoln Blvd.
Drivers also can expect the following closures:
- The N. 50th St. bridge over I-235 is closed through summer 2018.
- The I-235 on- and off-ramps at N. 50th St. are closed through summer 2018.
Learn more about the upcoming closure in this press release.

Allen Contracting Inc. crews guide the first steel beam for the new N. 50th St. bridge into place March 2 over the northbound lanes of I-235. Crews closed I-235 between N. 36th St. and I-44 at 7 p.m. March 2. The interstate reopened just before 6 a.m. Monday, March 5. The next full closure for the removal of the old BNSF railroad bridge is tentatively scheduled for early April.
ABOUT THE PROJECT
Part of the $88 million I-235 reconstruction starting at N. 36th St. will include rebuilding this BNSF railroad bridge over I-235.
Act 2 — I-235/US-77 and N. 50th St. — January 2017 through 2019
- This phase will widen I-235 to six lanes from N. 36th St. to just north of N. 50th St. It also will reconstruct the N. 50th St. bridge over the interstate, the BNSF railroad bridge and a smaller bridge near N. 50th St.
- This contract was awarded in May 2016 to Allen Contracting Inc. of Oklahoma City. Including incentives and a resurfacing project that prepared the interstate for the upcoming reconstruction, cost is estimated at $88 million.
- When awarded, this was the single largest dollar amount awarded for a highway contract in state history, exceeding contracts for the I-35/SH-9 East/Lindsey St. project in Norman and I-244 in Tulsa.
- Contractor will bring in national bridge experts to facilitate building the railroad bridge on site and moving it into place above the interstate.
- The demolition of the N. 50th St. bridge and the BNSF railroad bridge as well as moving the new railroad bridge into place will require up to six, separate full weekend closures of I-235 for traffic safety. Those closures will be announced later in the project.
- This is the third of seven phases necessary to complete the rebuild of the I-235 and I-44 interchange and this project combines two phases together.
- This project will address congestion and safety issues by providing six dedicated traffic lanes in addition to auxiliary lanes that will increase merging distance to accommodate current and future traffic.
- Regular traffic advisories will update motorists to lane closures and lane shifts throughout the project. Click here to read the traffic advisory for work starting Jan. 2, 2017.
Impact to Traffic
North and southbound I-235 is shifted between the I-44 interchange and N. 36th St. Traffic is shifted to the far outside lanes to make room for construction activities in the center lanes. The speed limit is reduced in this area. This project is scheduled to continue through 2019.
Drivers also can expect the following closures:
- The N. 50th St. bridge over I-235 is closed through spring 2018.
- The northbound and southbound I-235 on-ramps from N. 50th St. are closed.
ODOT encourages motorists to plan to be "Off Broadway" to avoid congestion during the more than two-year reconstruction project that started in January 2017.
Even with two lanes open in each direction, motorists are still encouraged to use their alternate routes as nearly two years' worth of construction work remains on the project, which is estimated to complete in late 2019.
- Suggested routes to help avoid traffic congestion include I-35 to the east and I-44 and SH-74 (Lake Hefner Parkway) to the west and I-40 to the south.
- The City of Oklahoma City recommends using N. Classen Blvd. and N. Martin Luther King Ave. for north-south travel and N.E. 36th St., N.E. 23rd St. and E. Reno Ave. for east-west travel into and out of downtown Oklahoma City.
- Motorists who need to access the state Capitol area may use Lincoln Blvd.

Act 2 Project Highlights
I-235 / I-44 construction footage from ODOT on Vimeo.
Here's a quick look at the many construction activities along northbound I-235 near N. 50th St. as of Sept. 22, 2017. Work includes ongoing improvements to the drainage system, which includes a 96-inch drainage pipe and a 72-inch drainage pipe. These much larger drainage pipes combined with more than 30 drainage structures along the 2-mile stretch of interstate are expected to significantly reduce flooding issues in this area during heavy rainfall.

Take a last look at how I-235 looked between I-44 and N. 36th St. before the first full weekend closure started June 2, 2017. The closure allowed for the removal of the N. 50th St. bridge span over the interstate among several other activities. The view was significantly different after traffic resumed early June 6, 2017. The contractor finished almost two days earlier than expected.
Crews worked nights to resurface I-235 between N. 36th St. to N.W. 63rd St. in order to have less impact to the nearly 100,000 daily commuters who use the corridor.
Curtain Closes on Act 1 — I-235/US-77 resurfacing from N. 36th St. to N.W. 63rd St.
- Night work started Aug. 22, 2016, and finished in late September 2016 ahead of schedule.
- Nearly $3 million contract with incentives was awarded in late spring to Haskell Lemon Construction Co.
- This interstate resurfacing was designed to improve the pavement condition ahead of a three-year widening project at I-235 and N. 50th St.
- Improving the surface condition now should lessen the potential for unexpected traffic disruptions due to the impact of nearly 100,000 vehicles a day traveling on fewer lanes.
Previous Phases of I-235 Reconstruction
- 2011 — Southbound US-77 ramp to westbound I-44 at $19.2 million. Shown on map above in yellow.
- 2013 — I-44 eastbound to I-235 southbound ramp at the I-235/I-44 interchange at $10 million. Shown on map above in light blue.
Once these projects complete, US-77/Broadway Extension and I-235 will be widened to six lanes, improving one of the worst bottlenecks for traffic in the state.
- Reconstruct I-235 between north of N. 50th St. through the I-44 interchange to N.W. 63rd St. Estimated $45 million.
- Flyover ramps/bridges of northbound I-235 to westbound I-44 and eastbound I-44 to northbound Broadway Ext. Estimated $35 million.
- Reconstruct westbound I-44 to northbound I-235/US-77 ramp. Estimated $16 million.
