| Located at the intersection of Fresh Pond Parkway and Concord Ave in Cambridge, MA, these paired rotaries are separated by about 200 meters. The western rotary has Fresh Pond Parkway entering from the north, and Concord Ave from the west; the eastern rotary has Fresh Pond Parkway to the southeast, Concord Ave to the east, and New St to the north.
These rotaries are heavily saturated from the funnel effect - all traffic out of Cambridge to the west must exit via Rte 2, located a half mile north of the donuts, or through Belmont on Concord Ave.
During 1999, 2000, and 2001, roadwork in between the rotaries has made traffic even worse than normal. |
