Gwinnett County school board members approved a staff proposal Thursday to spend about $3 million on 34 school buses.

Most of the buses seat 72 passengers while some seat 48 passengers, according to invoices from Peach State Freightliner, the company Gwinnett is paying for the buses. The 48-seat buses will be used for special education students, district officials said.

Gwinnett school administrators have said they need more new school buses because many in its fleet are more than a decade old.

The school board adopted a $2 billion budget Thursday for the upcoming fiscal year, which begins July 1.
