From the North:

Take Route 1A through Revere and East Boston toward Logan Airport. As the road enters the Logan Airport area, there will be a sign indicating a left fork leading to the Ted Williams Tunnel (right fork is for the airport; stay left). If your trip begins at Logan Airport, follow signs to Ted Williams Tunnel.

Travel through Ted Williams Tunnel and exit from right lane onto Exit 25. Exit 24 uses the same exit ramp, but stay right and follow Exit 25.

After the split from Exit 24, Exit 25 has two lanes; get into the left lane. There will be a traffic light just past the end of the exit ramp. Turn left at the light. After a couple of blocks there is a sign indicating that you are traveling on Congress Street. Continue on Congress Street through first traffic light. Shortly after that is a second traffic light; turn left there onto A Street.

After A Street passes under Summer Street (an elevated road in this part of South Boston ), the first right is Melcher Street. 49 Melcher Street is one block away, on the left, at the corner of Necco Street.

There is a new parking garage one block behind 49 Melcher, which can be reached by turning left onto Necco Street, traveling down one block to the end of Necco Street (you will see the garage on your left), and turning left at the end of Necco Street to reach the garage entrance. Alternatively, while still on A Street , drive past Melcher Street and continue (past an alley) to the next right turn (also called Necco Street, because Necco is L-shaped), which will bring you to the garage entrance.

There is also an outdoor surface parking lot on Necco Street, in addition to a few metered spaces (rarely empty however) on Melcher Street itself. Many visitors prefer the garage. Sometimes the garage has been full by mid-morning, however, reopening only later. There are a number of other surface parking lots within a few blocks of Melcher Street.
