Work Under Design:


Design work is underway on the following projects for letting sometime during 2018 and 2019.


250th Street Grading Project -  2.25-mile grade for paving project south of Anthon.   Right of way will be necessary to allow construction of this road.   Final design is complete.   Plats for right of way acquisition are complete and acquisition has started.  We have been delayed in further right of way negotiations in cooperation with landowners who have been busy with fall harvest.   We hope to resume right of way acquisition in December after harvest.   We are working toward a winter 2018 letting.  This project is funded with the $1.3 million per year special project levy funds.


Bridge D156 – This structure is on Franklin Avenue north of Old Highway 20/150th Street.  The structure is posted 8 tons.   The existing structure is significantly oversized and built from salvaged materials.   The replacement structure is proposed to be a large culvert.  This project is funded with money received in the local budget from the new $0.10 state fuel tax.  The project is scheduled for early 2019 construction.


            Haskell Avenue Bridge C-160 -  Design work and permitting are complete on the Haskell Avenue Bridge.   The new bridge will be a single span 100’ x 30.5’ pretensioned, prestressed concrete beam bridge.   Final plans are being prepared for a March 2019 letting.


Gravel crushing is underway at both the Railroad pit and the Briese pit. About 17,000 tons has been processed at the Railroad pit.    The crusher at the Briese pit broke down last week and production is just starting for the contract quantity.  


Mason Avenue Bridge:

            The Mason Avenue bridge was severely damaged by flooding on the Little Sioux River in July 2018.   The bridge has been closed to traffic due to damage caused by the bridge being struck by

a large tree.   The county engineer’s office was notified Wednesday that FEMA has determined that the damage is eligible for repair/replacement assistance.  The county road department is filing preliminary documentation requesting assistance from FEMA for assistance with eligible costs and will be having an applicant briefing on Tuesday, October 16th.   Communication is open with FEMA at this time to replace the existing bridge.   We expect that work to be completed in 2020 at this time.
