Work Under Design: 

Design work is underway on the following projects for letting in 2021.

1)         Design work is starting on a project to replace the K64 pavement from Highway 141 north to Old Highway 141.  This work includes new pavement through the town of Hornick.    The project is proposed for letting in summer or fall 2021.    

 

Other Projects:

1)         Work on the Iowa DOT bridge project on Highway 141 is complete and open to traffic.   The project was completed later than anticipated.    While Old 141 is no longer used as a detour route, the stop signs on the detour route will remain in place until spring when the rumble strips approaching the intersection can be patched.

 

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 is estimated to be less than $30,000 with FEMA and Iowa Homeland Security/Emergency Management Division paying the majority of the cost.   Work is expected to start Monday, May 3 on the project.

 

3)         Gravel excavation was let on April 5, 2021 for work in the Railroad Pit north of Correctionville.   The contractor plans to mobilize the second week of May.

 

5)         The pavement patching project let last fall is started on April 5.  The first project will be to replace settled bridge approach sections at the bridge east of Anthon on D38.   The approaches have been settling and a large bump has developed at both ends of the bridge.   D38 will be closed for about a week.   From there, they continued and completed all project work let last fall.   

 

6)         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 for delivery after July 1 to become part of the FY 2022 maintenance program.  The culvert will be placed by county road department crews.

 

7)         Stone Avenue east of Sioux City is closed due to a failed crossroad storm sewer pipe and intake structure.   The intake structure is not repairable.    A new precast structure has been ordered and delivery is expected the week of May 17.    Once it arrives, work will resume and the repair will be completed as quickly as possible.
