From the Maine Turnpike (I-95)
Exit from I-95 onto I-295 (I-95 Exit 44 from the south and I-95 Exit 52 from the north). Take I-295 Exit 6A (Forest Avenue South). After exiting, follow the signs to Route 77, which becomes State Street. From this point, follow the directions from Downtown Portland (below).
From Downtown Portland
Take State Street (it's one way) and go over the Casco Bay Bridge. At the traffic signal at the end of the bridge, proceed straight onto Broadway. (Broadway also goes to the right, but straight will take you to the museum.) Continue on Broadway until it ends at Spring Point Marina (approximately 1.5 miles). Turn right at the stop sign onto Benjamin Pickett Street and turn left at the next stop sign (Fort Road). Follow Fort Road through the SMCC Campus until it ends at the water. The museum is on your right.
