A railway bridge question: - what is the purpose of the narrow inner-track of rails that is found on most bridges? To me, it looks like a narrow-gauge track embedded in a regular track. - or is it just to strengthen the bridge? Here I am today at the Wellcox spur bridge over the Chase River, at Nanaimo:

To me, it looks like a narrow-gauge track embedded in a regular track. - or is it just to strengthen the bridge? Here I am today at the Wellcox spur bridge over the Chase River, at Nanaimo: They're called "guide rails". Those inner rails will hold a derailed set of wheels on the ties and track at least until it has left the bridge. They're just to prevent a derailed car from falling over while on a bridge.

A few more shots of the E&N Wellcox spur line bridge over the Chase River. The rail line leading to the bridge - very lightly used This is not nearly as thrilling to see as the Stoney Creek bridge or Ladner Creek bridge but it's simple and typical of many small rail bridges.

Welcome Dave. I saw that article, and I'm a bit sad. All practicality aside, I like the charm of a 1-lane bridge. - I'm not sure if the Chemainus river bridge is a true 1-laner, or just a 1.5 squeeze. But everytime I need to go from Crofton up-island, I like to take that bridge and then go through Chemainus.

What's being done with the old bridge material once it's gone? Are they going to create some kind of urban art with the metal, or just sell it for scrap?

It is certainly an interesting concept for me, doing urban planning... I don't understand why they don't just turn it into a greenway for buses, cyclists, walking, etc. which would keep the lighter side of transportation off the behemoth 10 lane concrete pileup? I look at it now and I have zero urge or interest in cycling over it... but if they create a more pleasant, easy environment, I would consider. They want to get people out of their cars, this is their big shot. I do not understand why they "need" to dismantle what appears to be a structurally and mechanically sound bridge. Can anyone speak otherwise of the current structure's condition?

Can anyone speak otherwise of the current structure's condition? Look at the Alexandria Suspension Bridge. It's crumbling and they're keeping it open to pedestrians. I definitely think that if it can stay open to light pedestrian traffic, the Port Mann can stay open to some extent. There's the maintenance money issue, but that's not my forte, so somebody else can rant on about that...

This is becoming a very popular reuse of abandoned elevated railway right-of-ways in NYC (http://www.thehighline.org/). I would love to see something like this done in Vancouver.

I hope you aren't suggesting the elevated Canada line sections . In the dusty recesses of my mind I think I remember a seldom used rail line (could be near Commercial?) that might be a good candidate if it hasn't already swallowed up by development. I know there is one that ends at False Creek, or has that become a trail already? We have the Beltline Trail that runs through the tony neighbourhoods of Moore Park and North Rosedale. It connects with a couple ravine trails and two subway stations, so it is quite popular but only known about by locals. I believe there is only one elevated section and bridge over Yonge Street, so not quite the Highline in NYC that is all elevated. Some bozo actually has suggested the highline approach for the main east/west expressway into Toronto, and the extensive elevated section called the Gardiner Expressway. They suggest moving the cars below onto city style streets. Stoooopid.

Here is a very cool pedestrian/bicycle bridge in Redding, California. It spans the Sacramento River and is part of a large park/botanical garden. We stopped by here on our drive down to California a week ago Monday: Here is a link to some information on the bridge: en.wikipedia.org/wiki/Sundial_Bridge_at_Turtle_Bay

A quick note for CV. The bridges you were looking at today at Alexandra in the Fraser Canyon are actually bridges 2 & 3. Bridge #1, the original, lasted from the 1860's to the early 1900's, was part of the original Cariboo wagon road, and was also a suspension type. I am sure more info on it can be found on Wiki. A nice photo essay, BTW. JST Yea, the original bridge was finally taken apart in 1912 after sitting damaged for a few years. A replacement wasn't built for years after, and is the old one you see today. Apparently the foundations of the original bridge are still visible, but after two visits in the past year, I've yet to find them. Luke, I was just reading the Wikipedia article Jim posted, and apparently the 1926 bridge was built on the footings for the old bridge, only 10 feet higher. This would explain why you can't find the footings.

Does anyone know why translink is raising the toll on the Golden ears bridge? Does anyone know where to Decals for the new port Mann Bridge and what does anyone know what it does to bill?

Does anyone know why translink is raising the toll on the Golden ears bridge? Does anyone know where to Decals for the new port Mann Bridge and what does anyone know what it does to bill? The toll on the GEB is staying the same as it currently is, to my knowledge. As for your second question, I'll see if I can rephrase it to what I think you're asking... "Does anyone know where to acquire/purchase decals for the new Port Mann Bridge, and how does Translink bill us for each crossing?" Your answer: I don't know what you mean by decals. If you mean the toll transponders, your Golden Ears Bridge transponders will work on the Port Mann. Mine worked on the Golden Gate Bridge and the SF Bay Bridge, because they use the same tolling system as the Golden Ears Bridge uses here. For billing, again, it will be done in the same manner as is done for the Golden Ears Bridge. They send you a bill in the mail every month, and you can pay either by mail, or online, or by bringing the bill to a Translink toll office. The only currently open toll office is in Pitt Meadows.

The decal is the thing for port mann and u own not rent for a monthly fee and it will work for ANY toll bridge in BC in the future. I read in the Langley times newspaper it going up.

CNR bridge over Fraser River at Lytton, BC. This is the bridge that includes a pedestrian bridge on the structure. It's accessed from town at the end of River St. - July 8, 2012: Walking across, with the town behind me: View from the south (non-town) side Down the pedestrian bridge in a cage, with a metal grate deck. The view from the bridge, looking north to the confluence of the 2 great rivers.

Does anyone know when u can start signing up for Decal, it says "late summer," when is the date when it starts? Does it save u money per-usage of the bridge on the Port Mann bridge or Golden ears Bridge or both? If, it doesn't for port Mann bridge or Golden ears bridge or both, what does it? And, does anyone how much it cost, and look likes?

Quebec Bridge: notice that the closer arch has been almost completly sandblasted & repainted, while the other arch as well as the middle section are still rusty and lacking a good paint job. This was due to an overbudget programme not too long ago. Thank you for this. I was recently reading about this rail bridge in one of my railway history books. Its design had a calculation-flaw, and it collapsed during construction. Then started again and completed.

Its design had a calculation-flaw, and it collapsed during construction. Then started again and completed. It actually collapsed twice. The second time, it was almost complete, and they were raising the center span section into position when it broke free and fell into the river. They say that one of the engineers realized the calculation error the morning the initial collapse occurred, and tried to get a warning to the bridge site but it wasn't in time. I recently watched of video of the train crossing the famous Forth bridge in the UK which is of a similar design, but much more massive in size.
