High-strength steel cables and concrete anchors embedded deep within the lake bottom are used to secure the pontoons and level out the bridge. When the water level rises, the pontoons rise with it, maintaining the horizontal alignment of the bridge.
How does a floating bridge work?
THE CONSTRUCTION PROCESS
Make the individual bridge pontoons on land adjacent to the waterway. The pontoons are then floated on water and towed by barges to the site of the bridge construction. The pontoons are individually anchored to the waterbed and each other, starting from each end.
How long is the floating bridge in Kelowna?
It is five lanes in width and almost 1063 meters in length. It remains the only floating bridge in Canada and is arched so that boats can pass under without a lift span.
How deep is the Kelowna bridge?
180 feet
The William R. Bennett Bridge in Kelowna is one of a very few floating bridges in the world. It crosses Okanagan Lake with the water depth of over 180 feet underneath the bridge.
Why are there floating bridges?
Most pontoon bridges are temporary and used in wartime and civil emergencies. There are permanent pontoon bridges in civilian use that can carry highway traffic. Permanent floating bridges are useful for sheltered water crossings if it is not considered economically feasible to suspend a bridge from anchored piers.
Does the floating bridge actually float?
These short-lived bridges might be made from wood or metal, and even inflatable tubes. Whatever their materials might be, floating bridges all have one in thing in common – they really do float.
How do you stop a floating bridge from moving?
I use Scotch double sided film tape, which is strong stuff, but won’t mess up the finish. It’s also super thin, so the floating bridge lays flat on the body. I simply peel off a strip of tape for each foot of the bridge, stick it on, and then place the bridge back in it’s original position against the blue tape. Easy!
Why did the floating bridge sink?
You may remember the floating bridge was made up of concrete pontoons. Prior to the disaster, engineers removed the pontoon’s watertight doors so they could work on the bridge. But when a storm arrived on November 25, 1990, the wind-driven water from the lake flooded the pontoons, causing the bridge to sink.
How often does the floating bridge Run?
The service operates for around 18 hours each day. It operates Mondays to Saturdays between 0500 and 0030 and on Sundays between 0640 and 0030.
How deep is the floating bridge?
It’s 1,640 feet (500 metres) long and 4.5 meters wide, built over a dazzlingly winding turquoise river. The water depth is 60meters. The bridge has a speed limit, to keep it from creating a big wave.
Why is Okanagan Lake so deep?
Approximately 10,000 years ago, the part of the Fraser Glacier that covered the Okanagan Valley formed an ice dam near Okanagan Falls as it melted, causing a large deep lake to form, known as Glacial Lake Penticton.

What is at the bottom of Okanagan Lake?
An eight-foot tall, 14-foot long sea monster resides at the bottom of Okanagan lake. It’s a life-size homage to the legendary N’ha-a-itk, better known to many as Ogopogo. A statue of the legend resides 30 feet beneath the surface at Paul’s Tomb, to the left of the bay in Knox Mountain Park.
Where is the largest floating bridge in the world?
Seattle, Washington
The new Evergreen Point Floating Bridge, which carries State Route 520 (SR 520), is the world’s longest floating bridge, stretching 7,708.5 feet across Lake Washington in Seattle, Washington.
Why does the water under bridges not freeze?
Most bridges today are built with steel and concrete, both of which are good heat conductors. Because these materials conduct heat, any heat that the bridge has moves through the bridge to the surface where the heat is lost through the air flow around it.
Which country has the largest floating bridge?
Nordhordland Bridge, Norway, 1,246 meters (pontoon section), 1994. This combined cable-stayed and pontoon bridge near the city of Bergen connects the mainland and the island of Flatøy, spanning Salhusfjorden, which is 500 m deep. It carries two lanes for cars and a pedestrian/bicycle path.
Where is a floating bridge you can drive on?
WHERE IS THE FLOATING BRIDGE LOCATED? The bridge sits in the Shiziguan scenic area in Enshi City of central China’s Hubei Province.
How do concrete pontoons float?
Essentially pontoons are hollow, watertight vessels. This structure enables them to utilise their buoyant character in support of weight which is equivalent to the amount of water they displace.
Can you block a floating bridge?
The gap at the front of the sustain-block is a problem when blocking a fully floating bridge. Fully floating bridges in these situations will need two blocks. One behind, as explained last week, and another in front of the sustain-block. The two blocks wedge the sustain-block between them.
What keeps bridges from falling down?
Abutment: Abutments are the elements at the ends of a bridge that support it. They absorb many of the forces placed on the bridge and act as retaining walls that prevent the earth under the approach to the bridge from moving.
Who built floating bridge?
An early pontoon bridge was constructed in 480 bce by Persian engineers to transport Xerxes’ invading army across the Hellespont (Dardanelles). According to Herodotus, the bridge was made of 676 ships stationed in two parallel rows with their keels in the direction of the current.
