At the bridges, Route 123 averages up to 30,000 vehicles a day and Route 7 averages up to 86,000.

Estimated Costs
Preliminary Engineering - $300,000
Construction - $2.2 million

The project is financed with state and federal State of Good Repair funding used for maintenance of structures and bridges.
