As
the big hand on the clock moves past 10, the nightly miracle begins. All
the players are in place, each poised like a participant in a carefully orchestrated
heist. At the head of the road are two police officers in their cruisers,
patiently waiting on the median. Along the left-hand shoulder is a line
of white and orange barricades and a team of four workers standing by. The
signal is called and each of these men makes his move. The cops switch on
their lights and swoop into the roadway, bringing the group of speeding cars
to a halt. The four workers grab the barricades and pull them into the road
one at a time, delineating a clear line guiding traffic off the highway to
the exit for Arthur Kill Road and the turnaround back to the Goethals Bridge.
One
of the cops then leads the traffic up the ramp while the other drives across
the span, checking it for stragglers. Once it's declared clear, the construction
crews crawl onto the bridge like an army of ants sweeping across
a picnic blanket, each lugging huge pieces of machinery and parts, setting
up camp for the night.
To
the average Staten Islander, the closing of the Outerbridge Crossing each night
is nothing but a huge inconvenience. They see the orange cones and flashing
lights and the next thing they know they're following the orange detour
signs to the Goethals Bridge.
And
the next day when they drive across the bridge, they rumble across the bumpy
surface, milled and exposed with huge steel plates concealing massive gaps
in the road. But the work that's being done is nothing short of miraculous
-- the tight coordination of construction crews, project supervisors,
police personnel and the hundreds of other men and women who came
together to make this project happen.
The
project is a three-year, $51.2 million deck rehabilitation, intended to extend
the life of the 72-year-old concrete bridge deck an extra 10 to 15 years.
If everything goes according to plan, the Port Authority of New York and
New Jersey, the agency that owns the crossing, will be back in 10 years to
replace the deck in its entirety. Until then, what's already there has got
to last.
Each
night since June the Port Authority shuts down the New Jersey-bound lanes
of the bridge. Once the lanes are empty, construction crews filter onto
the deck, some of them climbing up from underneath where the contractor has
set up a staging area, others driving trucks, cranes and other equipment onto
the deck from the start of the bridge on the Staten Island side. The
work crews -- some nights totaling as many as 50 people -- instantly take
their places. Within 30 minutes of shutting down the road, jackhammers are
already pounding away at concrete and steel. The night's work has begun. The
work must be completed each night inside a tight time frame of about eight
hours. On weekdays, the lanes must be reopened by 6 o'clock the next morning.
On weekends, they have a little more time -- they close it down at 11
p.m. but don't have to open it until 8 a.m. on Saturdays and 9 a.m. on Sundays.
Still, the time they have on the deck is precious.
While
the majority of each shift is spent working on the actual rehabilitation,
a large chunk of it is spent taking the roadway apart from the
night before and patching it back up to handle traffic the next morning. First
they drive the equipment onto the site. Then they pull the heavy steel plates
up, most of them covering works in progress -- a steel joint either in
the process of being torn up or a new one not yet finished being installed.
A
total of about 200 road joints, which allow the bridge to expand and contract
depending on the temperature, and hundreds of drainage scuppers will
be replaced during the course of the project. The roadway will be completely
milled and the nine-inch concrete deck below will be repaired and patched,
as well as the parapet walls alongside the roadway. The sidewalk along
the main span of the bridge will be replaced and the corroded steel structural
beams underneath the deck will be filed down and patched up. As the
crews move across the deck, large finished portions are then repaved with
a final smooth asphalt riding surface.
While
most bridge decks are replaced about every 40 to 50 years, the deck on the
Outerbridge today is the same one horses were pulling buggies across when
it first opened to traffic in 1928. Back in the mid-1980s, the Port Authority
did a major rehabilitation job on the span. And now the work is being
called on again to extend the life of the bridge. Sooner or later, though,
the deck will have to replaced.
Until
recently, the crossing never handled all that much traffic. For the majority
of its 72-year history, the bridge was little more than a country span
connecting one rural county to another. Today, it's the busiest of the Island's
three New Jersey crossings, handling more than 40,000 cars and trucks
a day.
A
walk across the bridge and a cursory inspection brings to light just how important
this project is -- rusted support beams, hollow concrete and corroded
road joints imbue the bridge from end to end. With each spike of vibrations
from the tractor-trailers rumbling across to Staten Island, the sense
of urgency seems clear.
Back
on the construction scene, the work is organized in a distinct pattern. About
700 feet of roadway on the Staten Island side is finished -- new road joints
have already been installed and the new asphalt riding surface has been
laid down. Further along, the road becomes milled and the concrete deck below
is revealed. Large square patches of fresh concrete dot the tattered surface.
A road joint is in its final stages of being replaced.
On
the next section of road a new joint has just been put in the road but the
concrete has yet to be poured. And further up the span, another team of workers
toils with an opening in the road where a joint has just been taken out
and the new one, pre-fabricated, sits along the side of the road. At the next
joint even further up the bridge, closing in on the top of the main span
where the road hasn't even been milled yet, workers are jackhammering and
firing the blow torch at the steel and concrete support around an old, rusted
joint that is about to be pulled up. And on the next joint, jackhammers
are firing away at the asphalt surrounding the joint -- the first
step in the lengthy procedure.
Crews
can work on a single joint for days at a time. And when 4 o'clock comes
rolling around each morning, they have to begin shutting down, covering
their work space with the steel plates and sweeping up the piles of asphalt
and crumbled concrete.
The
contractor is careful not to get to far ahead of himself -- the work has a
natural progression that helps him keep the project organized and makes the
bridge suitable to handle traffic each and every morning. On
another part of the span, a man sweeps the milled concrete deck with what looks
like a broom of metals chains, not pieces of straw. He listens carefully
to the sound it makes as it runs across the deck -- hollow sounds mean
those are the places where the deck must be ripped up and patched. "It's
a very simple, primitive technique, but it works and it's still the best
way to find where the concrete needs to be repaired," said Frank Gallo, manager
of bridge projects for the Port Authority.
The
man takes a can of spray paint and marks a box where he heard the chains call
out for help. Later that night or the following day, another team will come
by, rip the concrete up and pour a fresh patch. During
the night, the bridge transforms into a temporary city -- bustling with
activity and energy. But as the shift winds to a close, the machinery is
packed up, the holes are covered up, the masons, ironworkers, crane operators,
electricians, supervisors and laborers recede over the edges of the
bridge, and the next day the driving public has no idea what was going on
just hours earlier.
"To
me, the scale of the work and the overall scope of what we're trying to accomplish
is just amazing," Gallo said. "This may not seem as glamorous as building
a monorail at JFK Airport, but it's a complicated, involved project and
it's basically invisible to the public. Every night we close the roadway,
bring 25 pieces of heavy machinery out here, bring all these workers
up here, and then the next morning a person drives back over it like nothing
ever happened."
The
work is about to end for the season. Come November 15, construction crews
will seal the deck up for the winter and put away their cranes, jackhammers,
hard hats and concrete trucks.
Then
come next spring, the nightly ritual will begin all over again.
