Otter Tail County moves to repair structurally deficient Dead River bridge

A weak bridge on County State Aid Highway 1 near Ottertail could soon slow farm traffic, commuter trips and emergency response on a key link west of town. Otter Tail County is treating the Dead River crossing in Amor Township, about 4.2 miles west of Ottertail, as more than a routine maintenance issue after it was identified as structurally deficient.

County leaders are moving toward temporary repairs, load limits and an accelerated replacement plan to keep the span usable while a new bridge is designed. For farmers hauling grain and equipment, school buses, delivery trucks and residents driving between Ottertail and nearby communities, including Fergus Falls, Perham, Battle Lake and New York Mills, any restriction on the bridge can quickly mean longer routes and slower travel. If weight limits are posted, heavier vehicles would need to reroute, and if the bridge is closed during construction, the detour would touch daily errands and work commutes almost immediately.

The county has already shifted into project planning. In a request for proposals, Otter Tail County said it wants engineering services to remove bridge 56519 and build a new bridge on CSAH 1 over Dead River, with the goal of being ready for construction in 2029. The work is subject to Minnesota Department of Transportation State Aid requirements and the bridge waiting list, and the county said no federal funding will be used.

The schedule calls for design work in 2026, 60% design in January 2027, permit submittals in August and September 2027, 90% design in March and April 2028, easement acquisition in September 2028 and a desired bid opening in November 2028. County responses to bidder questions said the bridge site will be closed during construction with a detour, sidewalks will be built on both sides of the new bridge and pedestrian railings will be required. At the time of the question-and-answer period, adjacent residents had not yet been notified.

The bridge project sits inside a much larger transportation system. Otter Tail County’s highway department says it develops plans and policies for 1,067 miles of county state-aid highways and county highways, along with 74 bridges. County records also point to a 2021-2025 Highway and Bridge Improvement Plan that listed deficient bridges needing replacement or rehabilitation within five years, showing the Dead River span is part of a longer pattern of deferred infrastructure decisions. The county’s completed 2050 Transportation Plan is meant to guide future choices, but the test now is whether officials are acting early enough to prevent a small structural problem from becoming a broader failure.
