Voters approved an addition-and-expansion project at Nauset Regional High School during a special election on Tuesday.
The proposal passed in the towns of Brewster, Eastham, Orleans and Wellfleet.
The price tag is about 132-million dollars, but some of the cost will be covered through a state school building authority grant.
The new-and-improved high school could be ready in time for the start of the 2024-2025 school year.
