The section of Quarry Hill Road along Bruening Rock Products’ (BRP) quarry sees enough traffic to warrant dust control measures. 

That was the result of a recent traffic count facilitated by Iowa Department of Natural Resources (DNR) employee Clark Ott. 

Ott, who works out of the DNR’s Manchester office, recently counted 36 vehicles in a 30-minute period, which equates to 72 vehicles per hour. 

According to County Auditor Ben Steines, different DNR offices use different standards for dust control. The Manchester office dictates that gravel roads being used by more than 30 vehicles per hour need dust control. 

Since the beginning of the city’s Locust Road project, traffic on this section of road has increased as travelers are using it as an unofficial detour around the construction.

According to Winneshiek County Engineer Lee Bjerke, Bruening Rock Products is already implementing dust control measures in the form of watering the Road. 

At Monday’s meeting, the Winneshiek County Board of Supervisors agreed to share 25% of the cost of the dust control with BRP. According to Steines, a contractor will apply a dust-control substance, which is expected to last around 30 days and cost a total of between $3,000 - $5,000. 

“It’s difficult to say how long the substance will be effective. That depends a lot on the amount of traffic and the weather,” said Steines. 

The substance will be applied from where the pavement ends, south of the quarry, to the intersection with Highland Drive. 

Steines said the county plans to include Highland Drive on its next traffic study.
