BOSTON — Boston’s mayor says the large amount of snowfall from yesterday’s nor’easter is prompting a change in the St. Patrick Day’s parade route.

The parade will follow a shortened snow route to avoid snow pile up.

Mayor Martin Walsh says the route will allow “for a safe and enjoyable celebration,” and will help with traffic congestion for parade-goers on side streets.

Boston experienced blizzard conditions Tuesday, with officials estimating nearly 2 feet (0.61 meters) of snow fell in parts of Massachusetts, Rhode Island, Connecticut and Maine.

The St. Patrick’s Day Parade, organized by the Allied War Veterans’ Council of South Boston, brings between 600,000 and 1 million people to the city each year.

The parade route was shortened last year due to a snowstorm.
