June 30, 2021 – Redwood County contracted with Duininck Inc, the low bidder, to construct a new $4.6M bridge across the Minnesota River on County State Aid Highway 101. Unforeseen and very difficult foundation conditions initially delayed the project. The rock was extremely hard and uneven, resulting in the need to redesign the south abutment and caused slow drilling of ten foundation caissons thru several feet of bedrock. In an attempt to maintain schedule, the contractor worked thru the winter during some very difficult conditions. Work in the river during frigid weather proved inefficient and slow for Duininck.

Recently, during the concrete deck pour, the rails supporting the concrete paver failed, resulting in the contractor stopping the concrete bridge deck pour and installing a temporary bulkhead. The contractor is currently in the process of reconstructing this portion of the bridge deck by removing the concrete, replacing concrete forms and replacing the rebar before pouring again. After the bridge deck is finished, Duininck will need to complete the railing, north approach panel, high density concrete overlay, bituminous paving and erosion control. We expect the bridge project to be completed and open to traffic in September 2021. Through the teamwork of WSN, the bridge design consultant, MnDot bridge experts, the Contractor and County staff these challenges are being overcome and we expect a durable, long lasting bridge with a life of 75 years or more.
