Crews will close the left lane of eastbound Route 210 and I-435 beginning Monday, July 30 through Wednesday, August 8 (including weekends) for setting barriers, excavation and drill shaft installation work. Crews will also close the left lane of westbound Route 210 at I-435 from 9 a.m. to 4:30 p.m. daily during the same time period for bridge work.
Crews have rescheduled work in preparation for the demolition of the southbound I-435 Bridge over Route 210. Crews will reduce southbound I-435 at Route 210 to one lane from 9a until 3p Friday, July 13 for pavement marking and shifting traffic to a head-to-head configuration. Crews will southbound I-435 traffic to the northbound I-435 lanes. This work was originally scheduled for Thursday, July 12.
Crews will close westbound 210 Hwy at northbound I-435 from 11pm Friday, July 13 until Monday, July 16 for bridge demo work. Also closed during that time period: Eastbound 210 Hwy at Chouteau Traffifcway, the ramp from 210 Hwy to southbound I-435 and the ramp from southbound I-435 to 210 Hwy. These closures are in preparation for demolishing the southbound bridge over 210 Hwy.
Construction work continues on the building of the new westbound lanes of Route 210, west of the interchange. In order to construct these lanes, crews will need to move the westbound traffic onto a head-to-head configuration on the new eastbound lanes, which were constructed earlier this year.
Crews will close all northbound and southbound lanes of I-435 at Route 210 beginning at 10 p.m. Friday, March 2 through 5 a.m. Monday, March 5 for demolition of the now-closed flyover ramp. Traffic will be detoured to I-35 for both directions.
Crews are set to resume work on the project. The biggest impact to date will be the permanent closure of the flyover ramp from northbound I-435 to westbound Route 210 (Exit 55). Crews will close the ramp at 9 a.m. Wednesday, Feb. 28. The closure is in preparation for demolition of the ramp which is set to happen the weekend of March 2. Motorists wishing to travel westbound will need to exit at Route 210 and I-435 and turn left at the temporary traffic signal.
Crews have returned I-435 and Route 210 very close to its original configuration for the winter months. This project will resume construction in early spring or when temperatures allow.

About this project
The Route 210 and I-435 interchange currently serves nearly 100,000 drivers per day. This project will enhance capacity of I-435 by providing three continuous through lanes in each direction throughout the interchange.
Route 210 is an important freight corridor that serves multimodal freight hubs and was last summer from two lanes to four lanes from Eldon Road to MO 291. The new interchange will be able to accommodate the increased truck and vehicle traffic of Route 210.
This project will also remove the two uncommon high speed ramps to enhance driver expectancy and safety. Ramp reconstruction will enhance safety by providing increased storage and better turning movements. This project also includes the alteration of access at Randolph Road which will result in fewer traffic signal challenges and will improve safety.
