KDOT project to widen I-35 at 75th Street set to start in coming weeks

"What is ordinarily ‘rush hour’ traffic, looks more like middle-of-the-night traffic,” said Master Police Officer Danny Chavez from the Lenexa Police Department.  Traffic jams that were frequent on I-35 near the 75th Street exchange (pictured above in a file photo) are almost non-existent during the COVID-19 stay-at-home order. 

The Kansas Department of Transportation is planning to begin widening Interstate 35 from three to four lanes in a stretch of highway near 67th and 75th streets in the coming weeks.

The stretch of highway getting a fourth lane begins just south of I-35 at 67th Street and continues to just south of I-35 at 75th Street. Construction is slated to start in mid-March.

I-35 regularly experiences a bottleneck effect, especially during peak traffic times, because northbound I-35 merges with northbound U.S. 69 just south of 75th Street.

Kelly Kultala, public affairs manager for KDOT District 1, said the area will have some lane closures, but the highway is expected to remain open during construction.

During the first four months of the project, the southbound on-ramp to I-35 from 75th Street and the southbound exit ramp to 75th Street from I-35 will be closed.

“None of the lanes on I-35 will be closed,” Kultala said. “However, the contractor may need to have temporary lane closures from time to time reducing the current three lanes to two lanes.”

KDOT recommends vehicles detour at Shawnee Mission Parkway and take Antioch Road between 67th and 87th streets. Kultala said to expect traffic delays.

Construction is anticipated to be completed by mid- to late November.
