Transportation to Airport from Boston City Center

Logan Intl. Airport

The city of Boston, renowned for being home to Harvard University, the University of Massachusetts, Massachusetts Institute of Technology (MIT) and world famous health care institutions, welcomes thousands of patients, researchers, and students from all over the world. The only international airport in the city is the General Edward Lawrence Logan International Airport, also referred to as Logan International Airport. The airport is located 5.6 km from the city center and is accessible by ferry as a transportation alternative.

Airport Buses

The Silver Line 1 bus service provides transportation to Logan International Airport from the city center. This service departs from the South Station, which is located in the city center, in close proximity to many museums and the Boston Public Garden and Theater District. The SL1 line provides free transportation to the airport. Buses 459 and 449, which pass by the Summer St. stop, close to the Congress Bridge, also provide transportation to the airport. It takes a maximum of 20 minutes to get to the airport using buses 449 and 459.

Rail

Harvard University, the city center, and Cambridge are located along the Red Line, which runs from the north of the city to the south of the city. You can use this line to transfer to a bus to the airport. You can transfer to the SL1 bus at the South Station or transfer to bus 171 at Andrew Station. You can also take the Blue Line, which can be accessed from State Street Station, to the Airport Station. The Airport Station is located in close proximity to the airport. From that station you have to transfer to airport shuttle services to get to the airport terminals.

Ferry

Another transportation alternative to get to the airport is by ferry. The dock is a 10 minute walk from the city center. The ferry takes 18 minutes to get to Logan Wharf. From there the Massport Route 66 provides shuttle services to the airport terminals.

Taxi

Taxis are easy to find anywhere in the city and they are a convenient transportation alternative to get to the airport. Since the airport is located in such close proximity to the city center, about 5 km away, it is also considerably close to other important parts of the city like Harvard University, MIT, and the University of Massachusetts.

Car

The city center can be confusing to navigate but there are two tunnels that run under the Boston Canal, making the airport easily accessible by car. One of these tunnels is closer to the city center and is where the SL1 buses connect to the Red Line. To connect to this tunnel, which is located to the east of canal, take Summer Street, to Congress Bridge. After passing the bridge you can access the tunnel from Congress Street. The other tunnel is accessible by taking Merrimac Street north to New Chardon Street, which is on the right. This road will pass by Haymarket Square and take you directly to the west tunnel. This tunnel connects you to George Visconti Road, which provides direct access to the airport.

Airport Information

Handling more than 30 million passengers a year, Logan International Airport is one of the most important airports in the East of the United States. The airport contains a variety of services from children’s play areas to exhibition grounds, a September 11th memorial and recreation areas.

The airport offers passengers a rich selection of eating and drinking venues with over 50 restaurants and cafes, including fish restaurants befitting this seaside city.
