The Tonawanda City School Board approved three contracts Tuesday night that would provide students with disabilities transportation to schools outside the district.

The district chose a combination of providers to achieve an annual savings of $150,000: Transpo Bus Services, $168,000; First Student, $37,332; and an intermunicipal agreement with the North Tonawanda District that will cost Tonawanda $35 to $48 per student, for an anticipated cost of $125,000. The latter arrangement is pending approval of the North Tonawanda School Board.
