The School Department is starting bus runs earlier than usual Wednesday afternoon and Thursday morning, after buses experienced significant delays Wednesday morning as they traveled through traffic- and snow-clogged streets.
Wednesday was the school system’s first day back to classes after a snowstorm Monday forced cancellation of schools Monday and Tuesday.
The School Department said that about 20 buses were running more than an hour late Wednesday morning, heading to such schools as the Eliot K-8 in the North End, the Timilty Middle School in Roxbury, and the Lee Elementary School in Dorchester.
The school system also experienced a technical glitch because one of the radio towers on top of the Hancock building that is used to communicate with the buses was not functioning.
Mayor Martin J. Walsh acknowledged the delays, saying some snags were expected as the city recovers from this week’s snow storm and last week’s blizzard.
“Dorchester Avenue was tough today. I went down there,’’ Walsh said as he watched the Patriots parade from a balcony at City Hall. “A lot of Dorchester was tough.”
He added: “You have to expect delays in traffic. You have to go slower. Certainly, there’s a lot of frustration.”
The School Department said the district’s hotline was experiencing a heavy volume of phone calls.
“The safety of students remains our top priority, and we’ll continue to look at ways to improve performance this week, including some scheduling adjustments that get our first wave of buses on the road even earlier tomorrow,” said Denise Snyder, a school system spokeswoman.
