McCOOK, Nebraska -- The application rate of the oil on the two county roads set to get a new armor coating this summer will likely increase the projected cost of the 11 miles of roadwork.
Early estimates of $13,500 per mile could increase to $14,600 a mile because, county surveyor Gary Dicenta told Red Willow County commissioners Monday morning, "the road controls the application rate" of the oil. Dicenta said that both of the two roads that commissioners want to armor coat "are gong to soak up the oil" because they haven't been done in quite a while.
The Cambridge Lake road was last armor-coated in 1997 and the middle-or-so six miles of the Bartley-Lebanon road were armor-coated in 2003.
A contractor "will put on what the road takes," Dicenta said.
Commission Chairman Earl McNutt estimated the 11 miles will cost about $160,600. Commissioners try to resurface 10-12 miles of armor-coated county roads each year.
Commissioner Steve Downer said that Frontier County spent $15,000 a mile on the portion of the lake road in Frontier County.
Commissioners decided to advertise for two sets of bids.
The first bid will have the contractor haul the gravel from a sand pit to the construction sites.
The alternative bid will have the contractor use a stockpile of gravel at the location sites, and the county road crews will haul the gravel from a sand pit. Downer said it'll be good to know whether there's enough difference to justify the county transportation and manpower costs.
The roads are to be completed by Sept. 30.
Commissioners will advertise twice and open bids at 9:30 a.m., Monday, July 12.
