Hwy 70 current condition

In 2012 MnDOT did an extensive amount of maintenance work on Hwy 70 which included patching transverse cracks in the road. This work was done as a safety measure and to maintain the integrity of the pavement until the resurfacing project is done. MnDOT continues to monitor the pavement and will make necessary repairs as needed.

New sand-hauling activity has increased the number of trucks using Hwy 70. Some people have expressed concern that Hwy 70 will not be able to hold up with this additional traffic. The highway was designed to accommodate legally-loaded trucks and the structural design for the 2015 resurfacing project will also fully meet that requirement.

The life expectancy of the finished Hwy 70 resurfacing project is 20-years.
