The state Highway Department will begin a pavement repair this week that will close one lane of southbound U.S. 63 near the Columbia Regional Airport.
The pavement repairs will be done a mile north of the new U.S. 63-Route H interchange, and the work will be done between 7 p.m. and 5 a.m. nightly, beginning Thursday.
Officials expect the repair to be finished by Sept. 26.
MoDOT spokeswoman Sally Oxenhandler said the section being repaired is less than a year old, but already is having "some unexpected settlement of the fill placed in the area. As a result, we're working with the contractor who built the project to stabilize the underlying soil and lift the pavement to prevent further damage or problems."
Later, she said, other repairs "will involve some shoulder replacement and guard rail correction" in the same highway section.
Although MoDOT will direct traffic through the work area, motorists are urged to find an alternate route.
