This project is being done in coordination with a Plymouth County project on county route K49 in both counties.   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. Project work has started on the Plymouth County portion of the project.   Work is expected in the Woodbury County portion of the project in late August to earlySeptember.   Work in Woodbury County will be done under traffic control with a pilot car and flaggers maintaining traffic through the work zone.

The project allowed winter work at the contractor’s option and some work was completed. The contractor moved on site in January and removed the old bridge. Work on the project was delayed by spring flooding. The east abutment, east pier and west pier piling have been driven and all concrete work is done on those substructure elements. The west abutment piling are driven and the abutment will be poured Friday, June 28.   Falsework piling are in place and falsework construction is underway.

Work Under Design:

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

1)         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.   Preliminary design work is underway for a 209’ x 24’ continuous concrete slab bridge that meets the hydraulic requirements of this crossing.   There will still be road grade overflow on both sides of the bridge for extreme flooding, similar to the way the current truss has worked.   We will be submitting the design to FEMA shortly to obtain approval for an improved project.   We expect that work to be completed in 2020.             


2)         The county engineer is reviewing the cost to improve Benton Avenue south of 120th Street. The engineer will report estimated upgrade/improvement costs to the board ahead of their June 11, 2019 meeting.   Benton Avenue is a dead-end gravel road with several residences on either side of the road. For the second time in 10 years, the road suffered from severe instability during spring thaw. Options for improving the road to assure access are being explored by the Board and county engineer.
