BOW, N.H. (AP) — Officials say a bridge in New Hampshire is closed to all traffic after it collapsed.

Bow officials say the Birchdale Road bridge has been closed to vehicles since 2015 after an underwater inspection of the bridge showed it had structural deficiencies. The Concord Monitor reports it is now closed to all foot and bicycle traffic after it collapsed early Wednesday.

Town Manager Dave Stack says the bridge's culvert has deteriorated to the point where sand and gravel were falling through.

Bow voters approved a $772,000 warrant article for the bridge replacement in March. Town documents say $664,000 of the project will be paid for by state bridge aid available in 2025.
