Boston was hit with as much as 20 inches snow and public transportation via the Massachusetts Bay Transportation Authority (MBTA) was in some cases delayed or canceled.

MBTA Services said the Mattapan M-Line was suspended due to heavy snow. Substitute buses will replace regular train service while officials work to remove snow from the train tracks.

The Green Line D is being diverted because a tree fell down the tracks (bus shuttles will run between Newton Highlands and Riverside). For the Green Line E, service will terminate at Brigham Circle.

Due to slippery road conditions, MBTA buses will also omit many stops and connections.

MBTA Services said the Orange Line and Blue Line are running normally.

At Boston's Logan International Airport, all morning flights, about 400 in total, has been canceled, reported the Boston Globe.

Despite the snow-induced havoc, many Bostonian tweeted they successfully arrived to work after delays and sometimes traveling on alternate routes.

Made it into work today thanks to the #9 MBTA bus, although was running on delay, tweeted Julie Kepnes, a publicist.

Husband and daughter made it to work/daycare on red line porter to kendall no prob[lem], tweeted Adrienne LB.

Many Bostonians, however, are staying home as public schools are closed and Mayor Menino told non-essential public workers to stay home.
