One of the park's original rides, the Skyride offered what was considered a thrilling ride at the time
it opened. It still
offers spectacular views of the park and surrounding land, as well as a
means to cross the park and escape the heat of the summer days.
Original plans for the park featured multiple skyrides that were
supposed to connect the different areas along with trains, boats and
monorails. One plan involved a skyride that would have
linked Over The Rainbow (which would have been out past the Arena and
Log Flume) to the Enchanted Forest (which was planned for the area
beyond Nitro), which would have been more than twice as long as the
current Skyride.
Originally built for the 1964-65 New York World's
Fair in Flushing Queens, the Skyride was designed to handle large crowds
and during its 2-year run at the Fair offered a thrilling ride and
panoramic view of the attractions in Flushing Meadows.
Millions of Fairgoers rode the Swiss Skyride between the Switzerland and
Korean pavilions.
The ride was built by the Von Roll Corporation of Berne Switzerland, and
the colorful cars bore the companies logo on the doors. The
rounded aluminum cars were equipped with battery powered, roof
mounted lights which gave them a space age look.
The ride structure and cars were put into storage for several years,
until they were purchased for Great Adventure.
Assembly of the ride began in spring of 1974, with the pouring of the
large concrete footings at the stations which bear the load of the
cables. The steel station structures were secured to the
station moorings, and at the Fort end a large pit was constructed to
house the giant counterweights which provide constant tension to the cables,
no matter what the number of cars or the load.
The original six towers that support the cables were modified from the
original design used at the World's Fair, with angled cross arms
replacing the straight arms. In addition the original towers
used at the World's Fair featured open bases which ran half way up the
height of the tower, which were replaced with more substantial solid
towers at Great Adventure.
The towers were given a rich green paint color to make them blend in
with the surrounding trees of the Enchanted Forest.
The original cars from the World's Fair were given fresh coats of paint
in vibrant red, yellow, and green to make them stand out against
the trees and sky as they passed overhead.
With the Six Flags acquisition of
the park in 1977 came corporate sponsorship, and one of the first of
those sponsorships was Delta Airlines who sponsored the Skyrides at
several Six Flags parks. The cars were painted white with
red and blue roofs and the Delta logo was placed on the doors of the
cars. In addition the bottoms of the cars were fitted with
Delta's advertising slogan "Delta is ready when you are" and advertised
some of the airline's destination cities that it flew to from the New
York and Philadelphia area airports. This overhead
advertising was very effective and eye catching.
The Dream Street station of the Skyride is the end of the line that
supplies the ride's power, with large electric motors that turn the giant
pulleys, known as bull wheels. In addition, each line was
fitted with a backup gasoline engine that could be used to power the
ride for evacuation in the event of a power outage.
The gas motors were originally Volkswagen engines, chosen for their
reliability and simplicity. The main advantage they offered
was they were air-cooled so they required no radiators. More
recently the engines were replaced with larger diesel engines as parts
for old Volkswagen engines became more scarce.
The Skyride's signage has changed over the years with the changes in
park management and ownership. The ride plaques created by
Six Flags have even been updated with newer logos as the company's logo
has been changed.
Besides the sponsorship of Delta Airlines, the Skyride has also been
sponsored by Naturally Fresh Salad Dressings, and Ore Ida frozen foods

Adventure Skyride Fact Sheet
and Historical Attraction Plaque
The Fort station
features one of the main ride components which is rarely seen by many
employees, let alone guests. Under the station are two large
shafts which hold the two huge counterweights responsible for keeping
proper tension on the cables no matter how many cars or guests are on
the lines. The bull wheels at this end of the line have a
range of movement back and forth within the structure, and are attached
with steel cables to the counterweights below the floor.
As weight is added to the lines with additional cars or more guests in
the cars, the giant concrete weights rise. When there is less weight
on the lines, the weights lower and the line is pulled tight.
The two lines run in opposite directions (one clockwise, one
counter-clockwise) to facilitate the single set of stairs into the Fort
station that serves as the entrance to both sides.
Watch Video Of The Skyride In Action:
The ride towers
feature banks of rollers that guide the cable and the cars.
While outward appearance is that these wheels are all attached to a
single armature, they are actually grouped in sets of four, two and
four, with each set pivoting on a central point as cars travel over
them, as well as the entire wheel assembly pivoting from its center
point as the weight is transferred from side to side as the cars cross.
The flexing of the wheel assemblies is critical to the safe operation of
the ride, and is why they must be inspected for proper function on a
regular basis.
The "B" side of the Skyride features one additional tower which was
added after the ride was opened. This small tower located
just outside the Fort station gives the cable extra lift where the cars
pass over the Runaway Mine Train as it makes its final turn into the
station brake run. Apparently the clearance between the two
rides was much narrower than initially anticipated and the additional
support was added for safety.
The Skyride towers being some of the highest points in the park also
serve other purposes for the park, with emergency lights that come on
automatically in the event of a power outage attached about three
quarters of the way up the towers. At the base of several
towers are emergency generators which power those lights.
Atop one tower is a weather vane and anemometer which monitor the wind
conditions for the ride. Any time the wind gusts above
acceptable limits, the anemometer sounds a buzzer in the Dream Street
station, alerting operators to close the ride. In the event
of really large gusts, the ride will automatically shut down.
Another one of the rides towers has an antenna which acts as a repeater
for the park's walkie-talkie system, used to communicate between
employees and the various offices.
The Skyride is
frequently closed due to weather conditions. Its very nature
makes it more susceptible to wind than any other ride in the park, and
the length of time required to evacuate the ride and its elevation mean
that even with only a threat of thunderstorm activity in the area, it
must be closed for safety.
When the Skyride is running, it offers a relaxing escape above it all,
and with both sides running it can deliver the highest guest per hour
capacity of any ride in the park.
The Skyride cars currently
running were brought to the park from Six Flags Great America in Gurnee,
Illinois when they removed their two skyrides. These newer
skyride cars were lighter which allowed the addition of safety bars
which help keep guests from jumping or falling out.
The ride cars came to Great Adventure still bearing their Great America
logos, and were given the Great Adventure rainbow logo when the went
into service. Those logos have since been replaced with the
current Six Flags logo.
The ride originally had 112 of the rounded cars from the World's Fair
built for Von Roll by Gangloff AG. The 56 replacement cars from
Great America were built by Von Roll.
An Explanation Of How The Skyride
Works Mechanically:
The Dream Street
Station features six sidings for holding the cars when they're not in
service, three for each line. These sidings are accessed by
a series of switches that re-direct the guide wheels on the tracks.
The switches are operated manually with cables, and are balanced with
counterweights that hold them up in the open position normally.
When a car (or cars) need to be removed from the circuit, a lever is
pulled which lifts the counterweight and drops the switch track into
place on the rails. The cars are then manually pushed
backwards over the switch and onto one of the sidings.
The storage tracks are equipped with overhead catwalks used by the parks
Maintenance team to inspect and repair the cars' wheel assemblies and
cable clamps easily.
The Fort station also has a single siding for each cable.
These sidings are primarily used in the event a car needs to be removed
from service during the day (for maintenance or cleaning) rather than
for storage.
The storage area at the Dream Street end of the line was designed with
enough capacity to
hold all of the cars when the ride was not in use.
Each line also has one car used by the park's Maintenance team to
inspect and repair the guide wheel assemblies. Currently
that car is one of the original retired Skyride cars which has had the roof
removed. Inside, a platform has been added above the seats
allowing the workers to stand at eye level with the rollers. The
central post of the car has been fitted with attachment points for
safety harnesses.
At one point, a special red inspection platform car was on site (seen
below).
Inspections and maintenance are generally done very early in the
morning, prior to the park's opening for the day, so it is a rare sight
to see one of the maintenance cars in action. Watching the
brave workers so high in the air with (seemingly) so little to hold them
in place is not for the faint of heart!
Every few years the
Skyride is completely re-cabled as part of regular maintenance.
This involves removal of the old cable, complete overhaul or replacement
of the guide wheel assemblies, and the placement of a new steel cable.
Over time, the steel cable stretches, and for safety it is replaced.
Replacements seem to happen about every 10 years, with the last two
replacements occurring in 1990 and then in 1999. These
pictures from 1990 and 1999 show the Skyride in varying stages of the
re-cabling process. The towers without their signature wheel
assemblies and cables look very stark.
One of the trickiest parts of the re-cabling process is the joining of
the two ends of the cable to form one continuous loop with no visible
joints. This is achieved by a careful weaving of the steel
wires that form the cable together. The actual joint
stretches for several feet so all of the wire ends are spread out,
creating a smooth and strong connection which lasts for years.
