The Wisconsin Department of Transportation is soliciting bids for concrete deck removal and placement, approach slab replacement, and pavement replacement on State Highway 28 over the East Branch Rock River Bridge (B-14-067) in Horicon-Kewaskum, Dodge County, with bids due December 8, 2026. The solicitation identifies no set-asides.

The scope includes all incidental items shown on the plans and in the proposal. Bidders must submit a proposal guaranty and certificate of annual bid bond, subcontractor lists at least 48 hours before bid closing, debarment certifications, and non-discrimination compliance documentation. Work follows Wisconsin standard specifications for highway and structure construction (2025 Edition) and 23 special provisions covering asbestos abatement, bridge jacking, steel painting, bird deterrent installation, foam void filling, bearing cleaning and painting, and landscaping stone salvage.

Fish spawning restrictions prohibit instream disturbance from March 1 to June 15, and bird deterrent systems must be installed and maintained by April 14 to protect migratory bird nests. Contractors must notify the Bureau of Technical Services at least two weeks before ground disturbance at archaeological site 47DO704, located at Station 388+78. The project disturbs 0.03 acres and does not require WPDES Transportation Construction General Permit coverage, but cumulative land disturbance of one acre or more from contractor means and methods will require coverage. State Highway 28 closes to through traffic with a posted detour route.

Work begins within ten calendar days of written notice to proceed. Bidders must provide a proposed construction timeframe within one month of contract execution, with a conditional start date no later than March 15, 2027. Utility relocation by Alliant Energy (electricity and gas) is anticipated to be completed before construction, and the work requires coordination with concurrent projects 3364-02-63/65 and 3042-01-60. The contract requires prompt payment to first-tier subcontractors within ten calendar days of receiving progress payments and prohibits withholding retainage.
