Description:
T.Y. Lin International, in a joint venture
with HDR Construction Control Corporation, is providing design
review, construction engineering and field inspection services
for the new high-level, cable-stayed bridge across the Cooper
River. T.Y. Lin International also participated in the SCDOT
design review of the explosives threat to the new bridge. The
new Cooper River Bridge will link the town of Mount Pleasant
to downtown Charleston, ultimately replacing the existing Grace
Memorial and Silas N. Pearman bridges. Upon completion in 2006,
the bridge will be the longest cable-stayed span in North America.
Project Highlights:
- The new Cooper River Bridge is 2.5 miles in total length
and includes two major high-level interchanges on each end
of the bridge
- The cable-stayed crossing will carry eight lanes of traffic—four
in each direction—and will also feature a pedestrian
walkway/bikeway
- The main span is 1,546 feet long and will provide a 1,000-foot
navigational channel with a minimum vertical clearance of
186 feet above the Cooper River
- The new channel will accommodate fully loaded freighter
and container ships with a DWT of 54,000 tons, allowing
for much-improved shipping in Charleston Harbor
- Each 574-foot tall, diamond-shaped concrete tower will
be protected from ship collision by an innovative rock island
surrounding the base of the tower
