What you get when you cross a
highway project with an
urban renewal project. The major
components are:
The
Ted Williams Tunnel, which extends the
Mass Pike (
Interstate 90) east to
Logan Airport. This will also connect the
Southeast Expressway to
Logan; the
Boston end of the
Sumner Tunnel (SB) and
Callahan Tunnel (NB) (which carry
MA 1A) will be
reworked for
direct access only to the
north.
The
Central Artery, which is being rebuilt from
Andrew Square to
Charlestown, including a
tunnel from
Chinatown (where one already exists and will become the SB lanes) to the
Charles River and a new
cable-stayed bridge over the
Charles.
The
Leverett Circle Connector, which is a new bridge over the
Charles River with
direct access to
US 1 to the
Tobin Bridge and
Interstate 93. This also includes a
tunnel under
Leverett Circle for
eastbound traffic, which will complete
Soldiers Field Road and
Storrow Drive as a
freeway from
Harvard to
Interstate 93. There will still be a traffic light for traffic from
Storrow Drive to
Interstate 93 southbound though :(
The
Charlestown tunnel on
US 1, which was the first thing completed in the Big Dig. New
loop ramps were built to
Interstate 93.
Cost overruns have
plagued the project, which have been caused by
adding the
Ted Williams Tunnel and
mistakes in
measuring the
geography.
