Problems involving bus routes and congestion at the new East Bridgewater Junior-Senior High put a damper on the first days of school. New routes were posted on the School Department’s website last Wednesday, after what School Committee chairman George McCabe called “a lot of big glitches” that plagued the opening. “I’m disappointed with Lucini,” said McCabe, referring to Lucini Bus Co. of Bridgewater, the schools’ transportation contractor. “This is our third year working with them and we had no problems the first two years.” McCabe attributed the problems to software issues with the bus routes and new bus stops. With two more grades involved, McCabe said, the number of parents dropping off students at the Plymouth Street entrance to the new junior-senior high has also created problems. “People are frustrated for good reason and we’re trying to adjust on the fly,” he said.
