Im just interesting too see the newest design of these type of bridges
Lisbon is planning a third bridge over the Tagus river which wiil serv trains and cars so i supose it will be in a double decker system
Can u provide me worldwide photos of this bridges?

well iran is planning the persian gulf bridge witch will have cars and trains but there isnt enough info about the form of it yet. It will be 2.2 km long and it will link one of the biggest ports of iran with a persian gulf island of iran (the biggest island in the persian guld) called Qeshm

I don;t think this is exactly what your looking for but this bridge is crazy. Portland's steel bridge carries 4 lanes of traffic, two light rail Max lanes, 2 full rail lanes (bottom deck) and several pedestrian lanes.

Williamsburg Bridge: 8 lanes of car traffic, and two railroad tracks

There are a few others in NYC, but these two are the largest that carry both forms of traffic.

Sydney Harbour Bridge, Australia
Built 1926-32.

World's widest bridge, compared to its 'short' length (main span alone is 504 meters).
It remains the World's Largest Bridge with 8 lanes of traffic, two rail tracks, and a walkway/cycle way on its eastern side. Until the 1960's there were also tram tracks. In the 1990's a archclimb was opened for tourists.

Wow very interesting bridges u gotta love them :applause:

We dont have those in the netherlands nor in morocco.

There are a whole lot of bridges on the south island of New Zealand which are only a single lane wide with a train track, designed for vehicles in either direction and trains. I recall some of these being more than 100 metres long and guarded by nothing much more than a standard "give way" and "give way to trains" sign.

The Quebec Bridge (http://pedia.nodeworks.com/Q/QU/QUE/Quebec_Bridge/) is a cantilever bridge crossing the St. Lawrence at Quebec City. It's has three road lanes, one rail line, two walkways, and is located directly beside Canada's longest suspension bridge (the Pierre La Porte Br.).

I've been on the green one :D.

Only thing missing from a road/rail bridge is the pedestrian/bicycle lane(s).....come on now......EVEN IF THE BRIDGE IS 3-4 MILES OR LONGER......Don't forget or ignore the "human powered" mechanism in transportation.....hell even a segway could get on pedestrian/bicycle lane(s)........Jyeah!

There are no road and rail bridges in London. They are seperate, and this is probably down to historical reasons. When many of London's bridges were built, it was unphaesable to build road and rail, because of the technology etc.

The Blackfriars bridges are two parallel bridges that cross the Thames. One carries trains, and one carries road vehicles.

There are many bridges in Japan with both road and rail right-of-way, but until recently there was also a bridge in Japan that had both road and rail traffic, without grade seperation. It was located near Nagoya, and vehicles shared the road with trains from the Meitetsu Line, a heavy rail commuter line. It was called the Inuyama bridge, but now a new bridge was constructed that split the road and rail.

The Tagus River Bridge in Lisbon, Portugal, was completed in 1966, after four years of construction, for $32 million. It was originally named Salazar Bridge (after the then prime minister/dictator of Portugal, António de Oliveira Salazar), but, after the Carnation Revolution, in 1974, the bridge was renamed the 25 April Bridge (Portuguese: Ponte 25 de Abril), the day when the revolution occurred. In an emblematic picture of the revolution, captured in video, some people removed the letters saying "Salazar" and painted "25 April", instead of it.

Its total length is 2,277 m, the main span measuring 1,013m (17th largest suspension bridge in the world). It enbodies an important railroad line connecting Lisbon to the south, this line opened in 1999.

At the time of its completion it was the longest suspended span in Europe, had the longest main span in Continental Europe, was the world's longest continuous truss, and had the world's deepest bridge foundation (82 meters).

The Seto-Ohashi Bridges go from two of Japan's largest islands, Honshu to Shikoku, leapfrogging on smaller islands. This collection of bridges and viaducts is the longest road-rail bridge in the world collectively, but I think the Tsing Ma in Hong Kong is the longest for a single bridge. It carries 4 lanes of roadways and 2 narrow gauge tracks on 2 decks, with available space for 2 shinkansen tracks if it is expanded to Shikoku.

This is one of 3 sets of bridges crossing from Honshu to Shikoku- the Akashi-Kaikyo bridge (the world's longest suspension bridge) is part of these sets. The Seto-Ohashi is the only one with both road and rail service, though.

There are a small number of bridges in the South Island of New Zealand, which share between rail and road traffic, the interesting catch is that they are only one lane! Wouldn't want to stall on these bridges.

Cool bridges.....some of the ideas used are really interesting

high level bridge, newcastle upon tyne

Opened in 1849. The single carriageway road occupies the lower deck of the spans, and the railway the upper deck. The lower deck also provides pedestrian walkways.

I can't think of any more in the UK either, they've all been posted.

There's a great tradition of dual-traffic bridges here in portugal:


Constancia road-rail bridge:
- It's in the old Lisboa-Badajoz-Madrid railway
- the railway was being constructed in a double track configuration but around that location the contractors managed to get a permit to build the remaining route as a single track in the assumption that the major works (such as bridges) would be prepared for easy future duplication ... so the peers/pilars were built for double track but only one track installed.
- in the 90's (XX century as in 1990) they decided to upgrade the bridge for heavier loads so they build a new track over the UNUSED south side of the bridge and the old rail became a single lane road.

^^ I remember driving on this bridge in peak hour traffic and there was an ambulance behind us. There was nowhere to go. The ambulance just had to wait.

The government needs to build the second crossing ASAP. Screw the greenies and just build it before a disaster happens.

"There are four rail tracks on Sydney Harbour Bridge on both sides in 1932. The eastern pair of tracks must be removed later "

The two tram lanes on the eastern side of teh bridhe were converted to a bus lane and a lane heading east to the Cahill Expressway in 1963. The design of teh deck is shocking as well as it deteriorating quicker than the Bradfield design.

Bradfield was light years ahead of anyone else. :)

IIRC, the Huey Long bridge (Mississippi River) in New Orleans, LA is a combination road/rail crossing. Closer to home, one of the Saint Louis River crossings between Duluth, MN and the Superior, WI area is combination road/rail with WI 105 below and CN's ex DMIR Chicago-Western Canada mainline above.

There is a very lengthy road/rail crossing in central Brasil (road above/rail below).

Besides the Oresund bridge, we got a few more in Denmark:

Take the Storstroemsbro here. Its linking the poor farmer islands of Lolland and Falster with the main island Zeeland and Copenhagen, also, its the most direct rail to Germany from Copenhagen, and therefore the ICE goes over here, and on ferry to Germany, as far as i know, the only places in the world where a HST goes on a ferry :)
