BAMFORTH ROAD in Unknown County, Connecticut sits above 1% of rated Connecticut bridges on inventory load rating (16 t), while its 1978 build year is earlier than 35% of Unknown County's recorded-year cohort (208 bridges).
BAMFORTH ROAD in Unknown County, Connecticut is rated Poor in the FHWA's 2024 National Bridge Inventory. Built in 1978, it carries 3 rated components on the inspecting agency's 0-9 scale, and its weakest reported component scores 4.
