DSI demonstrates its technical Competence during Repair Work
on the Talmadge Bridge
The Talmadge Memorial Bridge is a four lane, cable stayed bridge in the state of Georgia, USA carrying US route 17 through
Downtown Savannah across the Savannah River to Hutchinson Island. There are two pairs of H-shaped pylons supporting
the stay cables. The main span of the bridge that was completed in 1991 is 335m (1,100ft) long, and the overall bridge length
is 3.1km (1.9mi).
In the summer of 2015, DSI was contracted
by the General Contractor, The Industrial
Company (TIC), to perform important
component repairs to the Talmadge Memorial
Bridge. As with all bridges, periodic repair and
maintenance is needed to keep the structure in
good condition, and this was the second time
DSI’s expertise was called upon for the repair
work. DSI had already supplied and installed
142
288 retrofit dampeners on the Talmadge
Bridge cables between 2006 and 2008.
The scope of DSI’s second contract was to
replace all the stay cable boot seals at the
pylons and underneath the bridge deck.
Furthermore, DSI renewed the cable stay pipe
tape where the existing tape had sustained
damage. The contract also included the
inspection and repair of all the anchorage
caps on the stay cables – both at the lower
anchor locations below the bridge deck
and at the upper anchor locations in the
pylons. The anchor cap repairs included
installing new seals, packing the caps
with new corrosion inhibiting compound
and replacing anchor bolts as required.
