Construction Project Report

 

To be let:

 

FM-CO97(136)—55-97, D38 HMA resurfacing project between Bronson and the Moville Blacktop. Letting date: July, 2019.   Late start date:  to be determined.    The project involves cold in place recycling of existing pavement followed by an overlay of the pavement with new hot mix asphalt pavement.   The project letting has been delayed as we have reached the allowable three-year borrow ahead restriction of our farm to market fund.  We now have to wait until we have accrued an adequate fund balance to let more project work to contract.   We hope fund levels will allow the work to be done in 2019.

 

FM-C)97(137)—55-97, K49 HMA resurfacing project between Plymouth County line and county route D12.   Letting date: February 19, 2019.   Late start date:  to be determined.   This project is being done in coordination with a Plymouth County project on the same county route.   The project involves cold in place recycling of the existing pavement followed by an overlay of high performance asphalt surfacing.    The high-performance surface provides a thinner overlay on top of the recycled pavement than standard hot mix asphalt.   This is Woodbury County’s first project using this material.  Work will be done in 2019.

Work Under Design:

 

Design work is underway on the following projects for letting in 2019.

 

1)         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 delayed right of way negotiations in cooperation with landowners while they were busy with fall harvest, but have now resumed that process.   We are working toward an early 2019 letting.  This project is funded with the $1.3 million per year special project levy funds.

 

2)         Bridge D156 – This structure is on Franklin Avenue north of Old Highway 20/150th Street.  The current structure is posted 8 tons.   The existing structure is significantly oversized hydraulically 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 2019 construction.

 

3)         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 finished and we are anticipating a March 2019 letting.

 

 

4)         Gravel Production - Gravel crushing is complete at the Railroad pit.   Production is suspended at the Briese pit and will resume when weather conditions allow. 

 

5)         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 that FEMA has determined that the damage is eligible for repair/replacement assistance.  The county road department has filed required documentation requesting assistance from FEMA with eligible costs and has started work on design of a new bridge at this location.    We expect that work to be completed in 2020 at this time.
