Motorists who use one of Oklahoma City's busiest interstate interchanges may want to give themselves more time to reach their destinations beginning next week.
Most of the construction will take place at night on the Interstate 44-Interstate 235/Broadway Extension interchange, according to the Oklahoma Transportation Department.
The construction mostly will affect eastbound motorists on I-44 who use the southbound exit to get on I-235 and westbound I-44 motorists who use the northbound exit to get on the Broadway Extension.
The project will replace the eastbound I-44 ramp to southbound I-235.
The new ramp will begin farther west on I-44 near Western Avenue and be tied into southbound I-235 farther south of the current ramp, near NW 50.
The work should be competed this spring.
It also includes work through August to lengthen and add a lane to the westbound I-44 ramp to Broadway Extension to help traffic flow.
The ramp is scheduled to be replaced in 2019.
Beginning Monday, the eastbound I-44 ramps to north- and southbound I-235 will close nightly from 8 p.m. to 6 a.m. through July 27.
The right lane of eastbound I-44 will be closed between Western and I-235 throughout the project.
Other than the overnight ramp closures at the beginning of the project next week, the plan is to keep the eastbound I-44 ramp to southbound I-235 open throughout the majority of the project.
Also beginning Monday, the westbound I-44 ramp to northbound Broadway Extension, the northbound I-235 ramp to westbound I-44 and the right lane of northbound I-235 between I-44 and NW 63 will be closed nightly from 8 p.m. to 6 a.m. through August.
The $9 million contract was awarded to Sherwood Construction of Catoosa, which includes incentives for early completion.
It's the second phase of a seven-part project to replace the 50-year-old interchange.
Total cost is estimated at $160 million and completion of the entire project is scheduled in 2019.
