Stretch of I-435 through Shawnee and Lenexa will be closed this weekend

Drivers in Shawnee and Lenexa should begin preparing for a temporary shutdown later this month of I-435 between Shawnee Mission Parkway and K-10 as crews replace the Renner Road bridge over the interstate.

While that stretch of I-435 is expected to be closed only for a few days, there will be longer-term disruptions to traffic around Renner Road itself, with the bridge replacement expected to take up to six months.

Here is what you need to know:

I-435 closure — March 18-21

Both directions of I-435 from K-10 to Shawnee Mission Parkway will be completely closed starting Friday, March 18, after the evening rush hour, at about 8 p.m.
KDOT officials expect to reopen that stretch of I-435 before the morning rush hour Monday, March 21
Official detours will use I-70 to K-7, then K-10 back to I-435, as well as I-70 to I-635 to I-35 and back to I-435
- Northbound traffic will detour via K-10 or I-35
- Southbound traffic will detour via I-70 or Shawnee Mission Parkway
