New London Schools haven't been in session since Monday after after the Blizzard of 2015 dumped about 30 inches across southeastern Connecticut.
With snow still covering many of the streets in the city Thursday afternoon, officials made the call to cancel school Friday.
"We did a practice drive with our buses and even though the roads were OK, the sidewalks were still a problem," said Tim Wheeler, chief operations officer of New London Schools.
He said about 40 percent of students walk to school, and with sidewalks still covered in many places, school was canceled for the fourth day in a row.
"We're watching the weather very closely," said Mayor Daryl Justin Finizio, as he toured part of New London with U.S. Sens. Richard Blumenthal and Chris Murphy.
When asked about school on Monday, Finizio said the school system "would be clear to go if not for the next storm."
"With another storm coming we will have to see and I will leave that decision to the superintendent’s office,” he said.
The mayor also said the city has been working around the clock to get roads cleared, adding that such a commitment meant that schools wouldn't be reached in time to get classrooms open.
The New London Schools Central Office is in a mode of transition currently, with a new superintendent set to start Feb. 1, right as the next storm arrives, bringing with it several more inches of snow.
"The first big decision he'll have to probably make is whether we have school Monday," Wheeler said.
