Lynn Saugus Bridge
Project
McDonald Electrical Corporation provided comprehensive electrical installation for the replacement of the Belden G. Bly bascule drawbridge on Route 107 over the Saugus River, connecting Lynn and Saugus, MA.
This public infrastructure project, led by SPS New England and designed by STV, featured a new 77-foot bascule span and required full electrical and control system integration. McDonald Electrical’s scope included:
- Motor & Span Drive Controllers: Installation of motors, brakes, and control systems for bridge operation.
- Power Systems: Emergency generator system, motor control center (MCC), and power distribution panels.
- Lighting: Navigational and general bridge lighting, roadway lighting, and lightning protection.
- Safety & Monitoring: CCTV, low-voltage power, traffic gates, and span locks.
- Control Systems: A modern bridge logic control system and control console.
- Submarine Cable Installation: Power and control cabling across the span.
Special Challanges
Work was performed over an active waterway with limited access, requiring coordination with the U.S. Coast Guard and careful scheduling around navigation windows. Crews managed precise alignment of moving components, coordinated with multiple trades in tight work zones, and adapted to evolving construction schedules.
Through expert planning and execution, McDonald Electrical delivered a reliable, high-performance electrical system that supports safe and efficient bridge operations.
