I-235/US-77 and I-44
Broadway Extension/I-235 & I-44 Interchange from ODOT on Vimeo.
Take a last look at how I-235 looks now between I-44 and N. 36th St. This view is significantly different after traffic resumed early June 6.
I-235 shifted at N. 36th St. through fall
North and southbound I-235 is shifted to the west between the I-44 interchange and N. 36th St. The speed limit is reduced in this area. This project is scheduled to continue through 2019.
Drivers can also expect the following closures:
Even with opening to two lanes in each direction, motorists are still encouraged to use their alternate routes as two years worth of construction work remains on the project, which is estimated to complete in early 2020.
Motorists should use SH-74 (Lake Hefner Parkway), I-44, I-35, I-40 and Lincoln Blvd. when possible as alternate routes and allow additional time while driving in this area.
ODOT encourages motorists to plan to be "Off Broadway" to avoid congestion during the three-year reconstruction project that started in January 2017.
- 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.
ABOUT THE PROJECT
Part of the $88 million I-235 reconstruction starting at N. 36th St. will include rebuilding the BNSF railroad bridge over N. 50th St.
Act 2 — I-235/US-77 and N. 50th St. — January 2017 through January 2020
- 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.
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 $42 million.
- Flyover ramps/bridges of northbound I-235 to westbound I-44 and eastbound I-44 to northbound Broadway Ext. Estimated $31 million.
- Reconstruct westbound I-44 to northbound I-235/US-77 ramp. Estimated $24 million.
