PAWTUCKET – While sharing buses with the William M. Davies Career and Technical High School seemed like a good idea on paper, Pawtucket families and officials have grown frustrated with the delays it has caused students both before and after school. “We aren’t doing a good service to our families in Pawtucket,” Erin Dube, deputy chairwoman of the Pawtucket School Committee, said at the March 25 meeting. “They want buses on time for their families.” To remedy the situation, school board members voted 6-0 to go out to bid for a new transportation contract without including Lincoln-based Davies. Member Joanne Bonollo was absent from the meeting.
