939 the Eagle’s LG Patterson reports motorists heading eastbound on Grindstone Parkway now have to turn right to head to the north. Some drivers have been confused and have been making u-turns.

What’s next: MoDOT says while the roadways have reopened, they say some work remains that may require single-lane closures.
