As the manhunt continues for a suspect in the Boston Marathon bombing case, mass transportation in and out of the Boston area was essentially halted Friday.
But while train and bus service have been halted for the most part, air travel remains ongoing at Logan International Airport as flights continue to arrive and depart.
Amtrak suspended service indefinitely between New York and Boston this afternoon, while intercity bus line operations were also shut down.
Commuter train service going into Boston also remain suspended, along with the city's subway system-known as the T-and city buses, including the Silver and Blue lines that run between Logan and the downtown area.
But despite the virtual mass transit shutdown, major highways remain open except for those in Watertown, Mass. because of police activity regarding the manhunt, according to the Massachusetts Department of Transportation.
And it is not just people within Boston that are affected by these transit changes.
More than 1,000 passengers were affected in cities including New York, New Haven, Conn., Hartford, Conn., Burlington, Vt. And Philadelphia after Megabus canceled nearly 22 bus trips going to Boston---according to the company's spokesman Mike Alvich.
Other bus companies, including Bolt Bus, Greyhound and Peter Pan Bus Lines suspended service as well.
