North
Carolina Department of Transportation and its contractors continue
working on Highway 12 on Pea Island and north of Rodanthe, where
breaches were cut by Hurricane Irene on Aug. 27.
The temporary bridge that will span the New New Inlet on Pea Island has
reached the south side of the inlet, and work crews began laying
asphalt on the south side of the inlet to connect the bridge to the
portion of Highway 12 that was washed out in the storm.
At the Rodanthe breach area, crews continued the fine grading of the
road bed in preparation of asphalt paving of the southbound lanes at
the s-curves. The first layer of asphalt base for the northbound lane,
south of the s-curves, was completed. Yesterday 17 truckloads of
asphalt were delivered to the project. Crews began excavation near the
roadway to install additional sandbags at the s-curves.
At the temporary bridge location on Pea Island, crews finished driving
all of the piles needed for this project. The framework for the
concrete footings at bent 1 was put into place. An additional
15
feet of the bridge truss was assembled and the bridge was launched
another 90 feet to the south.
Temporary Bridge Facts:
Piling: 82

Crews have made progress at both the Rodanthe breach area and the
temporary bridge location. However, there are still several tasks that
must be complete prior to the reopening of Highway 12.
These items are:
Pea Island
Bridge
Place
concrete for 4
footings;
Install a
backwall to
accommodate the transition between road and bridge on the south end of
the bridge;
Assemble
approximately 151 feet of bridge truss and launch the bridge truss to
the south end;
Remove the
temporary
roller bearings and lower bridge onto permanent bearings;
Put
grout/cement in
86 anchor bolts for the permanent bearings;
Adjust
bridge truss
for a smooth ride onto and off the bridge;
Install 12
devices,
which are 900 pounds each, to prevent uplift of the bridge in a storm
event;
Bolt
together and
install 610 steel deck panels to the truss floor beams to create the
riding surface;
Complete
backfilling
the retaining walls at the ends of the bridge;
Grade and
pave the
roadway approaches to the bridge.
Install
guardrail to
the approaches and both sides of the bridge; and
Pave 2-3
inches of
asphalt on the deck panels.
Roadway at
the Pea Island
Bridge and Rodanthe
Continue
fine grading
to shape the road bed for asphalt paving;
Pave
approximately
9,000 tons of asphalt;
Install
approximately
82 sandbags at the south end of the S-curves;
Reshape the
dune were
sandbags were installed;
Reconstruct
the
shoulder and reshape the dunes; and
Install
permanent
traffic control devices, reflectors and place pavement markings.
NCDOT estimates that the roadway could be fully reopened sometime in
early October, depending on weather conditions between now and then.
Much of the remaining work is very weather dependent.
In an effort to keep residents and motorists informed about Highway 12,
NCDOT has launched an N.C. 12 recovery website
(www.ncdot.gov/travel/nc12recovery) and twitter feed, and a
blog. To

(Slide show
photos show
the work on the temporary bridge at New, New Inlet and were taken from
the south side of the breach. Notice the remains of the old
U.S.
Fish and Wildlife headquarters that fell into the inlet a few weeks
ago. Other photos were taken at the S-curves north of
Rodanthe
and at Mirlo Beach. Notice in the video how long and wide New New Inlet
is, much longer and wider than Isabel Inlet in 2003 just north of
Hatteras village.)
