FAIRFIELD, Conn. — ­National Guard troops joined state crews to clear Connecticut roads on Saturday following a massive storm that dumped as much as 3 feet of snow, making travel nearly impossible, even for emergency responders who found themselves stuck on highways.

Governor Dannel P. Malloy said 270 members of the Guard were deployed to assist a storm recovery that he said could take several days. Some people who had been stranded in cars were found suffering from hypothermia, Malloy said.
