Map pilfered from MapQuest.com


The red star on the map indicates the location of the bridge but parking is best done on Island St.

Driving directions from Boston (45-60 minutes):

Take Rt. 93 N to Rt. 495 N. After a short while on 495 N, only a few exits, take the Marston St. exit--it comes up suddenly so watch out. I think the exit number is 44 or 45 but they seem conjoined somehow--it's a bit confusing. Cross over the river, loop around through a construction area, always following signs for Marston Street. Once the construction area is cleared take the first left on to Canal St. which is also marked with signs for outlet stores. Take the first left over the canal on to Union St. then the first left again (just on the other side of the canal) on to Island St. and park on the right, immediately. Walk back to Canal St. and take a left. The bridge is less than one hundred feet away.
