REGIONAL - Construction on the final section of Minnesota 60’s four-lane expansion - reaching from Windom to Mountain Lake - is expected to begin in late April.
That is, if spring arrives sooner rather than later.
“We’re going to need at least a week or two of warm or dry weather for the grade to dry out because we have a lot of earthwork left to do,” said Bob Williams, Minnesota Department of Transportation (MnDOT) construction engineer.
The new lanes are about two-thirds completed. Along with earthwork, MnDOT has to complete the westbound connection near Windom, resurface the new and old roads, install culverts and snow fences, and install J-turns at the Bingham Lake intersection. The project is expected to be completed by late fall.
“We’ve got a little bit of everything left to do,” Williams said.
Once the new lanes are completed this summer, both directions of traffic will shift onto the new road while the existing road is resurfaced and installed with culverts.
Roads intersecting with the highway will be closed off at times during the summer, including 510th Avenue in Bingham Lake for two weeks.
Mathiowetz Construction Company of Sleepy Eye has been working on the section of road since spring 2017. The company was the low bidder at $19.68 million.
Also in southwest Minnesota, U.S. 75 in Pipestone will be resurfaced to include a continuous two-way left turn lane in May. Pedestrian crossings in the area will be updated to meet Americans with Disabilities (ADA) standards.
