There's a fascinating US website called Bridgehunter - https://bridgehunter.com/ . Have a look at their list of longest bridges - https://bridgehunter.com/nation/report/longest/ . I cycled the Hudson bridge at Poughkeepsie the other year (https://walkway.org/) and despite the mist it was a stunning experience.

The Golden Gate Bridge at SF has to be one of the all-time great bridge rides for me (done it twice now!) - it's surprisingly steep to get to the mid-point .... although the bridge at Charleston in the US was also pretty good as a ride on my 61st birthday . . . riding across Brooklyn Bridge in NY is pretty cool, although not that long.

They aren't all cycle able, but it's a start.

There's something odd about this list. If the first Severn bridge is 1597m, which seems believable, than can the Second really be 5128m? It's not that much longer! I reckon their definition of 'bridge' is a bit inconsistent.

I think you're right, maybe for some it's the single spam and others the total length? Just reading through this thread you can spot some that ought to be on that list.

The "shore to shore" length of the new Severn Bridge is very lengthy, certainly waaaay more than the old one . . . but bridges are quite often expressed in record books as the measure of the longest span (e.g. the Humber was at once time the longest single span of any bridge in the world)

There are some "bridges" that I've driven over on the Florida Keys that really ought to be called "causeways" - they're just elevated roads across water and the odd islet/island.

I wonder what the longest ex viaduct is that you can cycle along?

The "old" Severn Bridge is two spans (one over the Severn, one over the Wye). The "new"* one is several. According to Wiki, the longest is 456 metres. https://en.wikipedia.org/wiki/Second_Severn_Crossing I reckon the 5,128m figure is probably including a lot of the elevated length over the land; as Rob says, it can be subjective as to where a causeway or embankment becomes a bridge. However you define it though, you'll have to cover 5,128m from end to end -- and unfortunately you're not allowed to cycle over it!

*It's 20 years old now; hardly new!

No advice here, but one idea you could try is a railway bridge. You'd need suspension to get over the sleepers!

The Tamar Valley Line goes over the Calstock Viaduct only a mile or two from where I'm sitting. The trains run every couple of hours and less on a Sunday, and it's not unknown for the locals to walk over on their way to/from Calstock/Bere Ferrers.


Hang on a minute we don't want a repeat of this tragic incident. https://en.m.wikipedia.org/wiki/Bere_Fe ... l_accident
At the last count:- Peugeot 531 pro, Dawes Discovery Tandem, Dawes Kingpin, Raleigh 20, Falcon K2 MTB dropped bar tourer, Longstaff trike conversion on a Falcon corsa. :D

Probably Fledborough - just under 900 yards, though it isn't really an ex viaduct it's still a viaduct. :wink:

Meldon Viaduct is only short (165m apparently) but worth a look if in the area

If you are referring to the above suggestion of the M5 then it's part of Sustrans route 41 and spans the Avon it also connects with Sustrans routes 410 and 26 .

Yes, tragic.
There's a memorial to the NZ troops at the station.
Can't happen these days, as it's a single track railway these days since the Beeching Cuts.

Even on lines known to carry no freight traffic, inspection, maintenance or weedkiller spray trains and railtour charter trains may run at any time. Passenger trains may be delayed and run at unexpected times. It is never safe to assume there is no train coming.
Observing adults who feel they are taking calculated risks trespassing on railways may encourage children to do the same in more dangerous settings.
I can assure anyone reading this, that folk walk across the viaduct.

The last train from Plymouth arrives at Gunnislake and then returns to Plymouth. It crosses the viaduct for the last time of a weekday night at about 22.30. Next time it comes back across, it's at 05.30 or so. People cross the viaduct after the pubs close shortly after the train I suppose.

I've walked across it and back .......... but legally ........... during the Centennial celebrations of the line. We paid a tenner each for the privilege.

Dornoch Firth Bridge 892 meters
Percussive maintainance, if it don't fit, hit it with the hammer.
