Construction Progress-Paving The Parkway
Paving is complete on the 42-mile mainline of the
Suncoast Parkway Project, including many of the local service roads and
the recreational trail. More than 400,000 tons of asphalt has been
used to complete paving of the entire project. The asphalt place on the
Suncoast Parkway is different than the asphalt historically placed on
roadways in Florida. It is SUPERPAVE, which stands for SUperior
PERforming PAVEment. It is a process new to the United States, but
widely used in Europe. This process provides an exceptionally durable
pavement, highly resistant to heavy truck traffic and wheel rutting.
Florida is one of six states utilizing superpave for state
roadway projects. The remaining states are all implementing superpave . The Suncoast Parkway Project is the second expansion
project by Florida's Turnpike using this new process. The first was the
Polk Parkway, which was completed in early 2000. The traveling
public may not visually notice any difference in superpave, but they
will see the benefits in the pavements ability to withstand the
ever-growing need for a quality roadway capable of handling large
volumes of private and commercial vehicles. This is just one of the ways
that Florida's Turnpike is paving the way for a safe and pleasurable
commute for our patrons.
Bridge Building
Bridge Building is a major component of the
construction process on all six sections of the Suncoast Parkway
Project. Whether the bridges are made from concrete or steel; whether
they are placed over existing roadways, streams, wetlands or rivers,
bridges are more complex and require more planning and preparation than
is first realized by the casual observer.
On March 29, 1999, eight bridge beams were set for the
Suncoast Parkway to bridge over State Road 50 (Cortez Boulevard) in
Hernando County. Many months earlier the bridge subcontractor built the
foundation by driving pilings to firm earth or rock. Then the road
building contractor put in the embankment and earth retaining walls.
When that was nearly complete, the bridge subcontractor came back to
construct the concrete supports ("bent caps") for the bridge
superstructure.
For the State Road 50 bridge, steel girders were
fabricated and assembled at Tampa Steel Company. Each beam was
approximately 170 feet long and weighted approximately 30 tons. The
girders were shipped in pairs, for stability, to the job site on March
22nd and March 23rd for placement by the bridge contractor. Motorists,
residents, and emergency services were given advance notice of the
beam's placement. Variable message boards, press releases, and articles
in local newspapers helped to alert all concerned of the intermittent
lane closures that would be necessary between 9 p.m. and 2 a.m. Local
law enforcement officers directed traffic throughout the evening.
LeWare Construction Company brought in two, 160-ton
American Cranes to set the beams. With one crane on State Road 50 and
one crane on the bridge embankment, they performed four lifts (two beams
per lift). This method consisted of the crane on State Road 50 and the
one on the embankment "walking" the assembled beams from the
south embankment across State Road 50 to their final position at the
bridge. To be successful, this operation required coordination by a team
including Turnpike construction, Turnpike safety personnel, ICF Kaiser
Inc., Prince Construction Company and LeWare Construction.
