HIGH ST
Carrying HIGH ST over RTE 1
OVER US1 1.5 MI E OF TL, Sagadahoc, Maine
Inventory: FHWA NBI 2024 · last ETL August 2026
FHWA NBI record, refreshed with each annual release.
HIGH ST in Sagadahoc, Maine sits above 53% of rated Maine bridges on inventory load rating (38 t), while its 1947 build year is earlier than 89% of Sagadahoc's recorded-year cohort (64 bridges).
HIGH ST in Sagadahoc, Maine is rated Fair in the FHWA's 2024 National Bridge Inventory. Built in 1947, it carries 3 rated components on the inspecting agency's 0-9 scale, and its weakest reported component scores 5. The lowest applicable rating sets the federal condition category, so this Fair 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.
