Bridge Snapshot: NASA ACCESS ROAD
The NASA ACCESS ROAD bridge in Prince George's, Maryland carries NASA ACCESS ROAD over BALTIMORE-WASHINGTON PAR. It was built in 1966, making it 60 years old today. It was last reconstructed in 2004, extending its service life. The structure is built primarily of steel and spans 6 sections, stretching 116.1 meters (381 feet) end to end. Daily traffic averages 10,000 vehicles, placing it in the moderately-trafficked tier of Maryland bridges. It is owned and maintained by Metropolitan Washington Airports Authority.
The latest FHWA inspection records show a deck rating of 6/9, superstructure at 4/9, substructure at 5/9. The weakest component sits in poor condition. A component scored 4 or below, placing this bridge in the federal Poor condition category rather than declaring it unsafe or closed.

FHWA National Bridge Inventory (NBI).
FHWA NBI Program ↗Condition Analysis
- • At 6/9, the deck (driving surface) shows fair condition, with minor wear flagged for upkeep.
- • At 4/9, the superstructure (beams and supports above the deck) is in poor shape, with advanced wear flagged for priority repair.
- • The substructure (piers and abutments) rates fair at 5/9, minor deterioration that routine maintenance should address.
How to read this record
NASA ACCESS ROAD is in the federal Poor condition category. That is a component-based result, not a closure order.
- NBI condition ratings reflect the latest record in this annual dataset, not a live status. Current routine inspection intervals are risk-based.
- Understand what Poor condition does and does not mean before drawing conclusions. Poor condition explained

- 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.
