Rural gravel road conditions were before the Tama County Supervisors during their regular meeting on Tuesday, Sept. 3. County Engineer Lyle Brehm said with the dryness of the soil and the gravel roads, it is extremely important for those using gravel roads slow down their rate of speed. Brehm said the high speed on gravel roads is causing an extremely large amount of dust which in turn means soil from the base of gravel roads is disappearing into fields and elsewhere.
Brehm was joined by board members in asking all those using Tama County gravel roads to slow their speed to 35 mph until there is rain. Brehm said this is important to keep the roadways in traveling condition.
Supervisors said a voluntary effort would prevent placing speed limits on gravel. Brehm said once there is a decent amount of rain this will not be a problem.
In the weekly road report from County Engineer Lyle Brehm, he says the bridge crew is working on a bridge east of High V18 on the Tama-Poweshiek County line. They will be replacing piles and some other deteriorated timber.
Brehm said rock on the shoulders of paved roads tends to not stay up tight against the pavement, and in time this leaves a drop off along the edge. Most years we can pull the existing shoulder rock up against the pavement to eliminate the edge drop, but periodically it is necessary to additional rock. The county likes to perform some of this work each year, and has just completed the placement of shoulder rock this year.
Highway T47 north of Gladbrook is part of an asphalt resurfacing project. All of the asphalt has been placed on the road. The yellow line down the center has been placed. Shoulders still need to be placed, and the white line along the edge will be placed after the shouldering is completed.
Highway E29 east of Garwin is also part of an asphalt resurfacing project. The final lift of asphalt still needs to be placed, as well as asphalt at the fillets and intersections.
Work on Highway D65 near Dinsdale continues. The old pavement has been crushed to leave a product similar to road stone. To address the soft subgrade along this road they are incorporating flyash into the underlying soils. The south lane has all flyash placed. The north lane still needs to have a portion treated with flyash. he contractor has started the process of spreading the crushed pavement out over the treated subgrade. Brehm says he doesn t know the contractor s exact timeline yet. Brehm says the road will soon be ready for the placement of asphalt.
