BOSTON (AP) — An emergency measure that made some narrow streets in South Boston one way when they became choked with snow during the winter may become permanent.

Mayor Martin Walsh on Tuesday announced that the one-way streets will remain that way for two more months while the city holds public meetings to determine whether the traffic patterns become permanent.

Walsh says the city received “a tremendous amount of positive feedback” about the one-way streets.

The streets were supposed to revert to two ways Wednesday but that has been pushed back until June 1.

The neighborhood’s major arteries remain two ways.

The city received 9 feet of snow this winter and giant snowbanks turned already narrow side streets into single-lane alleys that led to tense confrontations with motorists heading in opposite directions.
