Construction hits major Lakeville thoroughfare this week
Major reconstruction of County Road 70 between Kensington Boulevard and County Road 23 in Lakeville starts today and will finish in August in two parts.
The portion of the construction beginning today goes from Kensington to CR 9, and will finish in early July. The next portion, from CR 9 to CR 23, will be under construction from early July through late August. The segments will be closed to through traffic, resulting in detours.
In addition to an overall reclamation of the road’s surface, Dakota County crews will also install a new turn lane at the CR 70 and CR 23 intersection. This will result in a left turn, right turn and through lanes going eastbound. According to the County, this is a part of planning for future development in that area.
The method used for construction of CR 70 is called “Full Depth Reclamation.” In this method, the existing pavement is pulverized and blended with a portion of the underlying gravel, according to a County statement.
“The reclaimed material is then spread, shaped and compacted to produce a uniform graded base for new pavement,” according to the statement. “The contractor will then add several layers of new pavement on top of the reclaimed material. This process is being used because paving over the existing pavement would not correct the cracking.”
Improvements on a frontage road just east of CR 9 are also planned. This segment of the project involves curb replacement and road resurfacing.
