JACKSON COUNTY, MO (KCTV) -

Drivers throughout the Kansas City area have had to deal with construction-related traffic for most of the 2018 summer as crews work to repair the metro's many thoroughfares.

On Thursday, the Missouri Department of Transportation plans to begin another project that could delay Jackson County drivers up to 75 minutes.

MoDOT is scheduled to begin traffic control work ahead of bridge repairs along north and southbound Interstate 470 between E 39th Street and the Little Blue River bridge just south of U.S. 40 Highway beginning at 8 p.m. Thursday and lasting until Monday.

From 8 p.m. Thursday to 5 a.m. Friday, there will be intermittent lane closures along north and southbound I-470 between E 39th Street at the Little Blue River just south of U.S. 40 for pavement marking removal.  There will also be intermittent lane closures along westbound E 39th Street between Viking Drive and Arrowhead Avenue.

At 8 p.m. on Friday crews will begin intermittent lane closures along north and southbound I-470 for striping and barrier work until Monday morning.

Starting Monday, the same portion of I-470 will be reduced to one lane in each direction, as crews begin bridge repairs at the I-470 and Interstate 70 interchange, I-470 and U.S. 40, and the Little Blue River bridges on I-470. Crews will closed the outside (right) lane of both north and southbound I-470 between E 39th Street and the Little Blue River bridge until approximately early September.

The work will have major impacts to traffic with delays as long as 75 minutes expected during peak travel times.

MoDOT says motorists should expect that all loop ramps at the interchange to and from both I-70 and I-470 will be closed as early as Friday.

This includes:


The ramp from westbound I-70 onto southbound I-470.

DETOUR: Take the ramp for northbound Route 291. Take the 39th Street exit and make a U-Turn to get back onto southbound I-470.

  • The ramp from eastbound I-70 onto northbound I-470.

DETOUR: Head to Blue Parkway and make a U-Turn to get back onto westbound I-70 and then take the northbound Route 291 exit.

  • The ramp from northbound I-470 onto westbound I-70.

DETOUR: Use 39th Street as a U-Turn and then take the exit for westbound I-70.

  • The ramp from southbound I-470 onto eastbound I-470.

DETOUR: Take the ramp for westbound I-70 to Lee’s Summit Road. Make a U-Turn to get back onto eastbound I-470.


MoDOT is asking drivers to try to avoid the area if possible and those who must travel through the project should plan ahead and leave early. They ask that drivers be patient and courteous to fellow motorists and crews, use the zipper merge technique and take turns at the merge points. 

Officials say the project is the final phase of an extensive bridge rehabilitation project along I-470 that began in the spring of 2017.
