This document is a comprehensive set of construction plans for the Dorsey Lake Road Bridge Replacement project prepared by Coleman Engineering Company for the State of Michigan Department of Transportation (MDOT). The project involves the complete removal and replacement of an existing wood bridge structure spanning Dorsey Creek, with work beginning at project station 1+64.00 and ending at station 4+25.49. The bridge deck will be constructed of 15-inch Douglas Fir-Larch No. 1 lumber, with the superstructure utilizing glue-laminated rails and timber caps. The project includes demolition of the existing wood bridge deck, abutments, rails, curbs, and girders, along with removal and disposal of the existing road base to an 8-inch depth below the proposed road surface. Additionally, the contractor must perform grading, install erosion control measures including silt fencing and sandbag cofferdams, construct new abutments with stone riprap protection, and complete roadway improvements with aggregate base and topsoil restoration. The project area encompasses multiple wetland disturbances totaling approximately 2,388 square feet, requiring coordination with regulatory agencies.

The contractor bears full responsibility for traffic control in accordance with the Michigan Manual on Uniform Traffic Control Devices, including provision of warning signs, barricades, and temporary street closure notifications to local emergency services. All utilities shown on the plans are approximate, and the contractor must call Miss Dig at 1-800-482-7171 a minimum of three full working days prior to excavation to protect underground utilities in compliance with Michigan Public Act 174, 2013. The contractor is responsible for site visits to verify existing conditions, secure construction easements on private property outside the right-of-way, protect and maintain all existing utilities, and coordinate with utility companies regarding any necessary relocations. All timber must be treated with copper naphthenate preservative in accordance with AWPA UC4C specifications, and all hardware must meet applicable ASTM standards with galvanized coatings. Construction shall conform to current MDOT Standard Specifications and Plans unless otherwise noted, with the contractor required to submit shop drawings for all bridge components prior to fabrication.
