SIKESTON – Construction crews will be making driving surface improvements on Route 162 in New Madrid County. This section of roadway is located from Route M to Interstate 55 near Portageville. Work is scheduled between Wednesday, Sept. 6 through Friday, Sept. 8 from 6 a.m. to 7 p.m. daily. Open to local traffic only.
Seal coats are a pavement repair process that is used by MoDOT on roads with lower traffic volumes to maximize available resources and extend the life of the roadway.
The method costs about one third the amount of a traditional asphalt overlay. The treatment keeps water from penetrating the surface, extends the life of the roadway up to seven years, and provides improved traction.
