Maps of the area indicate Mission Hill development began before the Fenway and Longwood Medical Area. Huntington Avenue, now one of the main connections to the rest of Boston, once stopped at the intersection of Parker Street, near the present-day site of the Museum of Fine Arts. Up until that time, Mission Hill was connected via Parker Street (a man-made raised passage between the Stony Brook and the Muddy River – both which formed a tidal flat into the Charles River) all the way to Boylston Street in the Back Bay. Part of what was once Parker Street is now called Hemenway Street. The once main intersection of Parker Street and Huntington Avenue has been traffic-engineered, cutting the straight-line road in two and forcing traffic to first turn onto Forsyth Way to make the connection. Many other streets leading into Mission Hill were also realigned and/or renamed at Huntington Avenue (including Longwood Avenue/McGreevey Way, Smith/Shattuck Street, Vancouver Street, and Palace Road/Worthington Street), limiting both pedestrian and vehicular access.
