and Forbes Road, which run parallel to the north and south lanes of I-93 west of the split. The Crown Colony office complex in South Quincy and office buildings on Willard Street, the northern continuation of Route 37/Granite Street into West Quincy, are also accessed from the south via ramps at or next to the split. Short weaves, lane drops and line-of-sight problems all contribute to congestion in the interchange and the highways it serves. In addition to these issues, the split also serves the Quincy Adams subway station and Burgin Parkway, a major route into downtown Quincy, through ramps exiting the directional ramps for each roadway.
