Pavement collapse closes one lane of Hanley Road ramp to I-64

BRENTWOOD, MO - The Missouri Department of Transportation is calling in emergency support to re-open a busy on-ramp along Interstate 64 that collapsed.

MoDOT officials said they got a call from a driver about a hole on the shoulder of the Hanley Road ramp to eastbound I-64 due to a landslide. According to MoDOT, the slide occurred during Monday morning’s heavy rain and caused a section of the shoulder pavement to collapse.

“There is a drain pipe in that area, so whether that drainpipe failed and with all the rain that we had overnight, that just got a lot of water into that soil and caused it to slide,” said Karen Yeomans, an engineer with MoDOT. “Until we can really get in and do a geological investigation, we don`t know 100% for sure, but that`s kind of our theory,” she said.

Yeomans said the ramp will be open Monday night. MoDOT crews will have concrete barriers set up 10 feet away from the shoulder as a buffer zone so drivers will be safe passing the hole on the left.

“The biggest thing we would ask drivers, particularly tonight with a lot of parties tonight, is for drivers to be aware, for drivers to be careful as they go through that area and just pay attention and know that the lane is going to be narrower than they expect,” Yeomans said. “Just pay a lot of attention,” she added.

MoDOT said it will work to get a repair done quickly, but drivers should expect the lane restriction to still be in place when motorists return to work Wednesday after the New Year's Day holiday. Yeomans said MoDot is contracting a geological consultant team to inspect the underlying ground and work up a repair plan.
