Lane closures, delays on Highway 169 between Zimmerman and Princeton

PRINCETON – Motorists can expect short delays as traffic will be reduced to one lane as crews micro surface both directions of Highway 169 between Sherburne County Road 4 in Zimmerman and Highway 95 in Princeton beginning Sept. 11.
Work will be done in segments between 6 a.m. and 8 p.m., on good weather days, and will take up to eight days to complete.
Micro surfacing is a maintenance technique that has proven effective at extending pavement life of newer roadways at a fraction of the cost of resurfacing. The treatment is applied as a liquid consisting of asphalt, cement, aggregate and water. A Zamboni-like machine mixes and applies the material at a depth of around 3/8 of an inch.
