FHWA NBI record, refreshed with each annual release.

Fair
90 t Inventory load rating Higher than 96% of rated Colorado bridges

SH 83 ML in Douglas, Colorado sits above 96% of rated Colorado bridges on inventory load rating (90 t), while its 1981 build year is earlier than 87% of Douglas's recorded-year cohort (263 bridges).

SH 83 ML in Douglas, Colorado is rated Fair in the FHWA's 2024 National Bridge Inventory. Built in 1981, it carries 1 rated component on the inspecting agency's 0-9 scale, and its weakest reported component scores 6.

No NBI category is a closure decision or a live crossing-safety verdict.
