- Learn how the 0–9 condition scale and Good/Fair/Poor categories are defined. How condition ratings work
- Compare N46 against other structures in Harlan and across Nebraska. Nebraska bridges
- Noticed visible damage or a safety concern? Report it to the agency that owns the bridge, or call 911 in an emergency. How to report a bridge
Condition codes come straight from the FHWA National Bridge Inventory and are not a real-time safety judgment. Only the owning agency, a state DOT, county, or other owner, can post, restrict, or close a bridge.
