Dallas County Secondary Roads will be in the process of starting their 2014 construction projects this spring including a temporary road closure at P58/L Ave. Bridge at the South Raccoon River.

County Engineer Jim George brought the item to the Dallas County Board of Supervisors during their regular Tuesday meeting and stated the road would be closed for four to six weeks.

Cunningham-Reis Co., based out of Van Meter, was awarded the bid of $58,322 and will remove and replace the joints and approach pavements as part of the construction project.

According to George, a posted detour route will be located on old Highway 6 to Highway 169 to Interstate 80.

In addition to P58, secondary roads will be working on one of the largest construction projects this spring: Dexfield Road and 310th St. from Dexter to Redfield. The road, which was originally paved in 1968 is in need of replacement, according to Project Engineer Andy Case.

"The traveling public is well-aware that the existing pavement is tired and is need of replacement," Case said in a release. "The existing 6-inch concrete slab will be crushed and recycled as base and shoulder material to prepare for the 8-inch asphalt pavement, which will be placed in three layers. This should provide a solid road for many years to come."

Henningsen Construction, based out Atlantic, was awarded the bid at $3,252,092 to reconstruct the seven miles.

A public hearing will be held in Dexter and Redfield in late April before work begins. The road will be closed for two months although access will be provided for property owners.

Also on the county road’s construction season includes the replacement of Sportsman Club Bridge located two miles north of Adel. The bridge, which was built in 1957, will be replaced with a reinforced concrete box and will be bid out in early summer with a fall completion date.

The Indian Bridge over Panther Creek, located two miles south of Highway 44, will also be reinforced by Cunningham-Reis this summer at a cost of $58,975.

In addition to bridge construction projects, the pavement joints on the Dawson Road (D Ave.) from Highway 44 to 141 will be sealed. Denco Construction, based out of Mingo, will do the work for $139,555.

"The 25-year-old surface is in good shape and should stay serviceable for quite a few more years by sealing the joints," George stated.

The county currently includes 190 miles of paved roadways, 700 miles consisting of gravel, and 150 bridges which need regular maintenance.
