hen PCL Construction builds
a complex project, it makes
sure to put an emphasis on
safety. "The project team and
company care about the workers," Project
Manager Eric Chavez says. "It's just a great
company to work for."
The contractor is applying that focus to
its Lake Barkley Bridge project in Canton,
Ky., which will connect the state's Land
Between the Lakes area. The structure also
will replace the Henry Lawrence Memorial
Bridge, which was built in 1932 and recently declared obsolete.
When finished, the Lake Barkley Bridge
will widen 1.5 miles of the approach of US
68/KY 80 from two to four lanes. Each lane
will be 11 feet wide with four-foot shoulders and a 10-foot pedestrian/bicycle path.
This marks PCL's first project with the

Kentucky Transportation Cabinet (KYTC).
"They're a really good owner to work with,"
Right on Track
PCL won the contract for the Lake Barkley
Bridge project in February 2015, and it is

"We still have to complete the west approach sub-structure, girder erection, bridge
deck placement and all the finishes that are
required to put traffic on the bridge," he says.
After that work is done, PCL will demolish
the Henry Lawrence Memorial Bridge.
One of the major features of the Lake
Barkley Bridge is the 2,500-ton basket-handled network tied arch, which will be a
signature gateway entrance structure.

PCL erected it through the use of a float-in
system, Chavez recalls.
After erecting eight lifting towers on four
barges, "We floated the entire system with
the 550-foot span arch to the main channel,"
he explains, noting that PCL closed the
channel before securing the barges to the
piers and raised the arch 65 feet into the air.
Once the alignment was right, "We then
lowered the arch down to the bearings on
the piers," Chavez recalls, adding that the
