ANN ARBOR (AP) — Voters in the Ann Arbor school district have approved a $1 billion bond proposal, the largest in Michigan since 1994.

The district says the money will be used to upgrade schools, add classrooms, buy buses and technology, among other priorities. The Washtenaw County clerk’s office says the bond was favored by 53 percent of voters Tuesday.

The Ann Arbor district includes the city of Ann Arbor and parts of eight townships. There are 18,000 students.

Superintendent Jeanice Swift says the bond will “provide for generations of children.”

She says some of the 35 buildings will need to be replaced in the years ahead.

The Ann Arbor News says the district has a $9 billion tax base, the largest of any Michigan school district.
