BRATTLEBORO, Vt. — A ceremony is being planned to mark the completion a new Interstate 91 bridge over the West River in the town of Brattleboro.

The $60 million bridge project has been under construction for more than four years.

The single bridge replaces separate northbound and southbound bridges.

The ribbon-cutting ceremony will be held Tuesday at a bridge observation platform on Spring Tree Road in Brattleboro.

Republican Gov. Phil Scott will attend the program along with Transportation Secretary Joe Flynn and other officials.
