MoDOT to Seal Route 15 in Knox, Scotland, Shelby Counties

HANNIBAL - Weather permitting, MoDOT will apply a chip seal to Route 15 in Knox, Scotland and Shelby Counties beginning the week of July 6.

Operations will be from Route 136 in Scotland County to Route 168 in Shelby County. Traffic will be reduced to one lane between 7 a.m. and 4 p.m. with a pilot car leading traffic through the work zone. Work is expected to be complete by Thursday, July 16.

Chip sealing is a preventative maintenance measure that helps preserve the current condition of the road, but doesnt contribute to the smoothness of the surface. The project consists of placing a thin overlay of chips and oil on the roadway to seal and protect the pavement and extend the pavement life. The roadway can be driven on soon after applied, however motorists are encouraged to drive slow on the newly sealed road or to use an alternate route to avoid delays.

A few days after the chip seal is laid, a broom truck will go over the surface to remove additional rock, said MoDOT Maintenance Superintendent Rodney Osbourne. Vehicles help the process by mashing the rocks into the oil, so we wait a few days before we go back to remove the excess rock, he said.

All roadwork is posted on the MoDOT traveler information map on the day it begins and can be viewed on the online map at www.modot.org.
