Treasure County weighs culverts, quick fixes as DOT bridge replacement could take years
Summary
After River Road’s bridge was closed, Treasure County commissioners pushed for quicker interim repairs — including installing large culverts — while DOT funding for a full replacement could take multiple years. Staff were directed to pursue engineering estimates and present a plan in January.
Treasure County commissioners urged a faster repair plan for the closed River Road (Cove Bridge), arguing state-led replacement under Department of Transportation oversight could take years and leave residents without a primary route.
The board reviewed options presented by staff and consultants, including (1) maintaining the long-range MDT replacement plan using Senate Bill 536 funds; (2) a short-term “quick fix” engineered repair if feasible; and (3) installing large box culverts as a near-term, long-lasting alternative. Jim Atkinson of Southeastern Montana Development noted the county faces a narrow work window—“from October to April”—on irrigation-channel projects that affects feasibility and timing for any installation.
A commissioner argued in favor of the culvert option as the faster route: “I would like to go with choice 3 and use a culvert,” saying large culverts would restore width and weight capacity more quickly than waiting for a full bridge replacement. Commissioners also discussed potential environmental and permitting steps, including fish-and-game assessments required if in-stream work is necessary.
Officials stressed the tradeoffs: a DOT-led bridge replacement would preserve long-term state funding eligibility and match requirements but add design and federal-regulatory timelines; a quick fix or culverts could restore access within months but would require county-led engineering and possible local cost participation. Commissioners asked county staff to engage a bridge or culvert engineering firm to evaluate feasibility and costs and to bring a recommended plan to the January meeting so the county can act within available construction windows.
The decision leaves the county balancing speed of restoration against the prospect of leveraging larger state funding. The board did not vote on a specific repair tonight; it directed staff to report back with engineering options, cost estimates and permit needs at the next scheduled meeting.
