HWY TRM B DEP RD carries traffic over HWY LOGAN TRM B ARR RD in Suffolk County, Massachusetts. Built in 1979, this structure is 47 years old, placing it among the older bridges still in active service. The bridge features prestressed concrete construction with a girder and floorbeam design, a combination chosen by engineers to meet the specific requirements of this crossing.

Traffic data is recorded to help engineers understand usage patterns.

The bridge is currently rated in fair condition based on federal inspection criteria established by the Federal Highway Administration. The structure meets current safety standards for its designated use and load capacity. With a total length of 187 feet, this structure falls within the typical range requiring standard inspection procedures conducted by certified bridge inspectors.

Concrete bridges offer excellent durability and relatively low maintenance requirements. They resist corrosion well but can develop cracking over time, particularly in regions with freeze-thaw cycles or heavy use of deicing chemicals. Regular inspection focuses on detecting cracks, spalling, and reinforcement corrosion.

Federal law requires that all highway bridges be inspected at least every 24 months by qualified inspectors following the National Bridge Inspection Standards (NBIS). Some bridges with known issues or unusual characteristics may be inspected more frequently. Inspection data is reported to the National Bridge Inventory, a database maintained by the Federal Highway Administration that tracks the condition of all public highway bridges in the United States. This bridge data is sourced from that federal database and reflects the most recent available inspection results.
