FHWA NBI record, refreshed with each annual release.

Poor
23 t Inventory load rating Lower than 86% of rated Colorado bridges

SH 300 ML in Lake, Colorado sits above 14% of rated Colorado bridges on inventory load rating (23 t), while its 1954 build year is earlier than 71% of Lake's recorded-year cohort (17 bridges).

SH 300 ML in Lake, Colorado is rated Poor in the FHWA's 2024 National Bridge Inventory. Built in 1954, it carries 3 rated components on the inspecting agency's 0-9 scale, and its weakest reported component scores 4. The lowest applicable rating sets the federal condition category, so this Poor result describes the weakest reported component rather than the structure as a whole. No NBI category is a closure decision or a live crossing-safety verdict.
