When the Borough of North East, Pennsylvania, faced the need to extend the service life of the Wellington Street Bridge while managing long-term costs, B&N was engaged to evaluate rehabilitation options and guide early design decisions. Originally constructed in 1976, the 45-foot-span bridge carries an average daily traffic volume of 536 vehicles, making reliability and constructability key considerations for the community.
Data-Driven Analysis to Inform the Right Path Forward
B&N completed design services for the rehabilitation of the Wellington Street Bridge in North East. The project focused on assessing whether the existing non-composite steel box beams could continue to serve the community effectively if made composite with a new concrete deck.
B&N’s role centered on structural analysis and alternatives evaluation to support informed decision-making early in the design process. The team analyzed the existing beams to verify their structural capacity under composite conditions and compared that approach with full beam replacement.
Balancing Cost, Performance and Longevity
Analysis showed that the existing beams, when made composite, were structurally adequate. Rehabilitation costs were then compared with the cost of replacing the beams with new composite members. This evaluation also considered the potential increase in service life associated with new beams, helping the Borough weigh upfront investment against long-term value.
Minimal work is anticipated for the bridge abutments and approach roadway, allowing the project to remain focused on the superstructure and targeted improvements that provide the greatest return while limiting impacts to daily traffic.
Key technical considerations include:
- Structural capacity analysis of existing non-composite box beams
- Evaluation of composite action with a new concrete deck
- Comparative cost assessment of rehabilitation versus replacement
- Consideration of long-term service life in alternatives analysis
Construction is expected to begin in summer of 2026.
