This is a construction drawing set for a bridge replacement project issued by the Michigan Department of Technology, Management and Budget (DTMB) and the Department of Natural Resources (DNR). The project involves the removal of an existing bridge structure over Marsh Creek on the St. Helen-Geels ORV Trail in Richfield Township, Roscommon County, Michigan (File No. 751/25246.RLO), and the construction of a new segmental precast concrete box culvert measuring 44 feet by 8 feet. The drawings were prepared by OHM Advisors and issued for construction on August 5, 2026. The project includes approach work, guardrail installation, riprap placement for slope protection, and site grading. The structure is designed to HL-93 Modified loading standards with deflection not exceeding 1/800 of span length. The existing structure, a railcar frame bridge with wood deck, will be removed prior to construction. A temporary steel multi-beam bridge overlay will be removed by MDNR before construction begins. The project requires stream diversion methods, debris prevention and removal measures, and immediate slope protection and seeding upon abutment completion.

Design specifications reference the Michigan Department of Transportation 2020 Standard Specifications for Construction. The culvert is designed for a 100-year water surface elevation of 1177.34 feet with a proposed stream bed elevation of 1172.50 feet. Soil boring investigations have been conducted at two locations with results documented on the boring logs sheet. The project includes guardrail approach terminals (Type 2M, Modified) with 28.1-foot height transitions and Type T guardrail with 96-inch posts on both approach sections. All work must comply with concrete clear cover requirements (3 inches for concrete cast against earth, 2 inches for all other applications), and exposed concrete corners must be beveled with triangular moldings. The structure has been evaluated using FAA obstruction evaluation pre-screening tools for a 150-foot height above ground level, and no FAA permits are required. Road traffic closure will be maintained by MDNR throughout the construction duration, and all construction must account for potential water level variations subject to regulatory approval by the Land and Water Management Division of the Michigan Department of Environment, Great Lakes, and Energy.
