Pont Samuel-De Champlain

I wonder how much it would cost to make something like Norways Helgeland bridge (picture below).

It has 12-lanes and it is over 1 km long, it probably cost anywhere between C$62 million - C$132 million to build. True it is 6000 meters shorter than the Champlain.

 

Donc le pont Champlain fait 7km de long? Alors 132*7, ça donne 924M$, soit environs le coût estimé de la reconstruction seule du pont Champlain. Le reste de la facture - 5MM$, c'est pour les "dommages collatéraux", qui sont le déplacement des voies d'accès existantes, les voies d'accès temporaires, la mise à niveau des routes de part et d'autre, mesures de mitigations, etc.

 

Ton pont en Norvège m'a l'air dans le milieu de nul part. Mais il est très joli.

Sometimes i wonder if we shouldn't approach this problem from a different angle...

 

If bridges are expensive to build over the Saint-Lawrence partly because of the lengthy spans, why not shorten the spans? A massive land reclamation project could shorten the Saint-Lawrence effectively making it easier to build bridges and tunnels while simultaneously providing fantastic

development opportunities. Of course, to cross the channel bridges would still need to be high so there's still that.

It's an absolutely crazy idea and it wouldn't happen, never in a million years, but i still think it's an interesting "what if" idea to ponder.

 

Then again, maybe land reclamation isn't so far fetched...

Obviously it would be expensive, but one can dream...

I think the problem with that, is we already have enviro-nazis going bonkers about something that would if anything reduce pollution, and land reclamation projects usually have a significant effect on the aquatic ecosystem.

 

Then again I would half-expect those people to completely not care about it or even be in favour especially if it gets dedicated as "green space" :rotfl: We did do something similar but on a small scale in the 1960's, but we did everything in the 1960's including psychedelic drugs. Did you downgrade (yellow-out) the end of the Bonaventure? LOL!

 

Just as an aside, the Montreal archipelago is really interesting for all these islands, everywhere! They are so delicious to develop (as was Nun's Island) but bridges so expensive...

Land reclamation on the scale you are talking about would probably cost in the 10's of billions$. Even though it would be expensive, I like your idea. The only problem with it is that the new bridge wouldn't be lined up with A-10.

There is what looks like a park there at the end of his highway stub... why not run that freeway further to Victoria St then turn Victoria and that nasty side of Taschereau into a freeway splitting nicely into the existing A-10. You can even go the other way too and link up with that 112/116 freeway, would be a nice distributor to the South Shore and support densification of the area...

I just wanted to point out that what you are referring to as a Park, is in fact the Country Club de Montréal. ONe of the oldest, if not THE oldest golf course in Montreal. The whole concept of "taking a Mulligan" was started at the course.

One of the oldest, but the oldest Golf Club in North America is the Royal Montreal Golf Club (1873) now situated on Ile Bizard. It used to be located in Dorval. That may be the one you referred to.

Why does everthing inQuebec cost 10 or 20 times more than anywhere else????

 

Take a look at this a mere 19 years ago and it<s a combo tunnel bridge over 4.6 miles!!! thats what 2 or 3 times longer than the Champlain...Tabernak!!!

 

 

mmmbt_1.jpg

The Monitor-Merrimac Memorial Bridge-Tunnel (MMMBT)

 

The structure is the Monitor-Merrimac Memorial Bridge-Tunnel (MMMBT), a 4.6-mile long combination bridge-tunnel system

The MMMBT opened in April 1992 after seven years of construction and a total cost of about $400 million.

 

Salient features of the bridge are:-

 

1. It is 4,800 feet long from portal to portal.

 

2. Built by the immersed sunken tube method

 

3. The traffic lanes in the tunnel are 13 feet wide, with 2.5-foot-wide ledges on either side of the roadway, and with 16.5 feet of vertical clearance from the roadway to the ceiling.

 

4. Traffic flow is monitored from a traffic management center where employees keep an eye on operations through 33 closed-circuit television cameras.

 

5. Seventy-two sensors in the pavement of the tunnel and approach bridges automatically check every 20 seconds for interruptions in traffic flow. In the event of an incident, motorists are advised of alternate routes via 32 electronic message signs activated immediately from the traffic management center.

 

6. While traveling through the Monitor Merrimac, motorists do not lose their favorite local radio station while in the tunnel. A communications system rebroadcasts all local AM and FM radio stations. In the event of an emergency, tunnel staff can override these broadcasts with emergency information motorists receive through their vehicle’s radio without changing stations.

Akashi Kaikyo Bridge

Vital Statistics:

Location: Kobe and Awaji-shima, Japan

Completion Date: 1998

Cost: $4.3 billion

Length: 12,828 feet

Type: Suspension

Purpose: Roadway

Materials: Steel

Longest Single Span: 6,527 feet

Engineer(s): Honshu-Shikoku Bridge Authority

In 1998, Japanese engineers stretched the limits of bridge engineering with the completion of the Akashi Kaikyo Bridge. Currently the longest spanning suspension bridge in the world, the Akashi Kaiko Bridge stretches 12,828 feet across the Akashi Strait to link the city of Kobe with Awaji-shima Island. It would take four Brooklyn Bridges to span the same distance! The Akashi Kaikyo Bridge isn't just long -- it's also extremely tall. Its two towers, at 928 feet, soar higher than any other bridge towers in the world.

The Akashi Strait is a busy shipping port, so engineers had to design a bridge that would not block shipping traffic. They also had to consider the weather. Japan experiences some of the worst weather on the planet. Gale winds whip through the Strait. Rain pours down at a rate of 57 inches per year. Hurricanes, tsunamis, and earthquakes rattle and thrash the island almost annually.

 

How did the Japanese engineers get around these problems? They supported their bridge with a truss, or complex network of triangular braces, beneath the roadway. The open network of triangles makes the bridge very rigid, but it also allows the wind to blow right through the structure. In addition, engineers placed 20 tuned mass dampers (TMDs) in each tower. The TMDs swing in the opposite direction of the wind sway. So when the wind blows the bridge in one direction, the TMDs sway in the opposite direction, effectively "balancing" the bridge and canceling out the sway. With this design, the Akashi Kaikyo can handle 180-mile-per-hour winds, and it can withstand an earthquake with a magnitude of up to 8.5 on the Richter scale!

 

Here's how this bridge stacks up against some of the longest-spanning bridges in the world. (total length, in feet)

 

 

Akashi Kaikyo Bridge 12,828'

Fast Facts:

The bridge is so long, it would take eight Sears Towers laid end to end to span the same distance.

The length of the cables used in the bridge totals 300,000 kilometers. That's enough to circle the earth 7.5 times!

The bridge was originally designed to be 12,825 feet. But on January 17, 1995, the Great Hanshin Earthquake stretched the bridge an additional three feet.

The bridge holds three records: it is the longest, tallest, and most expensive suspension bridge ever built.
