Commodore Barry Bridge Biennial Inspection

Spanning 13,912 feet across the Delaware River, the Commodore Barry Bridge serves as a vital link between Chester, PA and Bridgeport, NJ.

HNTB has worked for the Delaware River Port Authority to help ensure the continued safe operation of their four long-span bridge facilities by leading thorough inspections since 2004.

The biennial inspection of this critical cantilever through truss bridge includes field inspection and evaluation of all existing structures, including nonredundant steel tension members and fatigue-sensitive details across various spans. Work involves underwater inspections, acoustical imaging of river piers and rock islands, ultrasonic testing of truss pins and inspection of vibration dampeners. These efforts will culminate in the issuance of the current 2024 Biennial Inspection Report, Bridge Condition Certificate, and completion of bridge inventory forms for Pennsylvania and New Jersey.

Providing ongoing support to DRPA, HNTB will also conduct six-month interim special inspections, on-call damage inspections, and drone inspections of selected areas. Rerating of approach bridges and main bridge approach spans will be executed using Load Factor Rating and Load and Resistance Factor Rating methodologies, factoring in as-built and as-inspected conditions with AASHTOWare Bridge Rating and CSiBridge.
