 Now that the Fourth of July weekend has passed, more road construction projects are starting across Minnesota. Andrew Krieger reports. With holiday traffic in the rearview mirror, the next stage of the summer construction season begins. That includes the start of a two-year project along U.S. Highway 12 in central Minnesota. MnDOT says the first phase includes closing a stretch of Highway 12 between Litchfield and Dassel from this week through about July 20th. Crews will be working on culvert replacements and concrete repairs.
