Main Street Signal Upgrade

Project Overview
This was a Montana Department of Transportation project to improve traffic flow along Main Street. The first phase of this project installed new traffic signal controllers at every signalized intersection along Main from First Avenue North to Wicks Lane.

The project also installed communications grade interconnect wire between the signal controllers. This allowed the controllers to "talk" to each other and adjust signal timings based on actual traffic conditions along Main Street.

The communications interconnect also allows City signal technicians to monitor signal operations and diagnose equipment problems from their offices on Edward Street. A second phase of the project included collecting extensive traffic data to develop new signal timing plans for the whole Main Street Corridor.

Estimated Cost
Total estimated cost of the work was $750,000. The project was funded by the Montana Department of Transportation, but relied heavily on City traffic engineering personnel for implementation.
