The Problem
The Route 250 highway bridge in Sandusky, Ohio had a corroded electrical supply enclosure powering its street lights. The old unit was rusted and falling apart, creating an unsafe area, not sustainable for the future. The unit contained a power-supply load center with interior conductor circuits that were too large to put in a standard breaker. The challenge was to create a more permanent solution to continue providing light for the bridge.

The Solution
Milbank engineers were able to replace the outdated, rusting unit with a more clean, safe and secure power source solution. The new aluminum enclosure contains a load center and is raised off of the ground with a concrete base. The updated power source unit now includes terminal blocks in order to accommodate larger conductors and has room to grow with more components in the future like additional circuits, photocell, hand-off-auto switch and more.
