[3] The Carlton Bridge was repaired in 1997 by Wright Construction Co., Inc. of Mount Holly, Vermont.

Work began with dismantling the bridge to provide access to the bottom chord; reusable pieces were stored in a nearby field.

Crews replaced rotted wood throughout the bridge, including the trusses, floorboards, and rails.

The repairs cost $414,025, with the State Bridge Aid Program covering 80 percent.
