  • Directions to 30 Winter Street, Boston

    Commonwealth Care Alliance is located at 30 Winter Street at Downtown Crossing in Boston. Our reception desk is on the 6th floor. Winter Street is primarily a pedestrian walkway, so there is no parking outside our building. Wheelchair-accessible parking is available on Temple Place, near Winter Street.

    Public Transportation

    Commonwealth Care Alliance is located between the Park Street and Downtown Crossing “T” stations.

    Park Street serves the red and green lines; Downtown Crossing serves the red and orange lines. From either station, exit to the street and go down Winter Street. 30 Winter Street is 1/2 block from either station. 30 Winter Street is also easily accessible by the Washington Street silver line; exit the silver line at the Downtown Crossing/Temple Place bus stop, and go through the accessible passageway to connect with Winter Street.

    If you do get off the train at Park Street Station, go up the stairs that say Tremont Street / Suffolk University. When you get to the street level you will see Winter Street (a pedestrian roadway lined with bricks). Proceed down Winter Street about 40 seconds and on your right you will see Santander Bank and TD Bank (take a right). Our entrance is actually on Winter Place (an alley of sorts). You will see the entrance to our building on your right – a large banner saying #30 Winter Street.

    Driving Directions

    We recommend that you park in the Central Parking Theater District Garage, which offers reasonably priced parking convenient to our office (we can provide you with a $5 parking discount coupon). The entrance is on Boylston Street. Use the address 30 Winter Street, Boston, MA 02108 on your GPS.
