Work Under Design:

Design work is underway on the following projects for letting in 2020.

  • Design work has started on Port Neal Road from the Iowa DOT rest area to Gelita.   The work is scheduled for late 2022 or 2023 construction.

Other Projects:

1)         Old Highway 141 was used as a detour route while work on the Iowa DOT bridge project on Highway 141 was underway.   The stop signs placed temporarily at the intersection of K67 and Old 141 have been removed.

2)         Letting for Wolf Creek DD repairs was on March 30, 2021 and awarded to Johnston Excavation.   The project involves bank repair and debris removal.   The project is funded by FEMA and drainage district funds. Cost to the district landowners is estimated to be less than $30,000 with FEMA and Iowa Homeland Security/Emergency Management Division paying the majority of the cost.  Work started the last week of May and should be completed by the end of this week on August 6th.

3)         Gravel excavation was let on April 5, 2021 for work in the Railroad Pit north of Correctionville. The contractor has completed this work.   The county let and awarded the crushing of the material to Hallett Materials on August 3, 2021 and the material will be crushed and produced to meet county gradation requirements.

5)         The county engineer requested quotations for repair to a small bridge on County Home Road west of Bronson.   The west abutment piling failed this winter, and the bridge has been closed since the first week of March.   We requested quotes to drive new piling and replace the west abutment cap, but we only had one quote for the work that was deemed to be too high.   Quotes have been obtained for a precast concrete box culvert to replace the bridge.   A new culvert will be ordered to replace the bridge. We had originally anticipated delivery after July 1, but due to supply chain issues, delivery has been delayed into mid-August. The culvert will be placed by county road department crews.

6)        Production of approximately 20,000 tons of gravel is underway at the Briese Pit.   The county is paying $3.75 per ton for production of this gravel by a new contractor, Bedrock Gravel.
