From ODOT:

"I-35 narrows at US-77/SH-66/Second St. in Edmond beginning Monday
I-35 will be narrowed between US-77/SH-66/Second St. (mm 141) in Edmond and N.E. 122nd St. (mm 137) beginning Monday, Sept. 25, for pavement rehabilitation through summer 2018. Motorists are strongly encouraged to plan for an alternate route. Drivers can expect intermittent ramp closures and the following lane closures:

The right lane of southbound I-35 will be closed between 33rd St. in Edmond and N.E. 122nd St. from 7 p.m. to 6 a.m. nightly Monday, Sept. 25, through Friday, Sept. 29;
The right lane of northbound I-35 will be closed between 33rd St. and US-77/Second St. from 7 p.m. to 6 a.m. nightly Monday, Oct. 2, through Friday, Oct. 6; and
Additionally, motorists can expect I-35 to be narrowed to one lane on weekends starting in mid-November."

This is extremely poor planning/timing by ODOT. They are closing lanes and doing construction on I-35 now? While Broadway Ext'n is under a major rebuild? And Hwy 74 still isn't finished north of Kilpatrick Tnkp?
