    "Rows of bollards which appeared unannounced along George IV Bridge were installed after fears were raised that heavy trucks could plunge through the weak pavements and land on the Cowgate, the Evening News can reveal."

    Is that when the bike racks appeared too?

  2. Oh I love the fact the councillors are getting their knickers in a twist over the bollards being trip-hazards and so on, then in the picture all you can see between them are sandwich boards.

    Lovely too that this quote: "I suspect a lot of people have hurt their leg because these things are too low" has become the first line of "A MYSTERY which has left traders and tourists scratching their heads – and rubbing their bruised legs – has been solved"

    I have a vague memory of Laidback mentioning it was to stop pavement parkers?

    "He said: “We needed something physical to stop these vehicles parking on the pavements and going through the basements into the Cowgate.”"

    Didn't the railings/bike racks do that?

    In other news, people astouned to find out that a Georgian bridge built to take sedan chairs, dandy horses and nothing heavier than a horse and cart can't take the weight of a 12 tonne lorry parking up on the pavement

    "Didn't the railings/bike racks do that?"

    Yeah but they weren't "Streetscape" enough.

    And more bike racks would just have encouraged, um can't think how to finish that sentence.

    These are the same type of bollards as found on Royal Mile I think.

    These allow two bikes parked between each. Saves having untidy bunches of bikes upsetting the streetscapers...

    What! You mean George IV Bridge is actually a bridge! Who'd have thunk it!

    Just for once the comment made me laugh.

    "Ah yes. Elisa Esposito, 38, who owns Cafe Lucano and is not an engineer of any sort said “I’m not entirely convinced that a truck could fall straight through the street but they have obviously done the research.”. Maybe they have, just go back to serving the coffee. "

    Could a heavy truck not easily plunge straight through a weak bollard onto the pavement? Heavy trucks are capable of some fairly impressive plunging when they put their minds to it.

    Don't think they're there to stop plunging, just to stop pavement parking.

    I’m not entirely convinced that a truck could fall straight through the street

    Should we start a poll?

    • A: Truck will simply crush kerbstones
    • B: Truck will cause cracks in basement wall
    • C: Truck will enter basement requiring even larger truck with crane to dislodge

    Presumably the bridge is less strong towards the edges since it has less area to spread the load before it reaches the edge. I'm guessing that if something were sufficiently heavy and sufficiently close to an edge the bridge could crumble at that edge and cause the heavy object to plunge.

    It does show you something that they have to justify bollards for stopping people parking on the pavement in some other manner.

    Isn't truck on not terribly wide pavement enought. Mind you, an industry led and funded proposal of hunners of sandwich boards would do the same for nowt.

    I think we need a George IV Replacement Crossing.

    It wouldn't cost much. Growth in China has slowed (now only 7.5%) so there must be plenty of cheap(er) labour available.

    Wagons (and cars, for that matter) on pavements are a pet peeve of mine - the number of broken paving slabs that result from this...

    I've got some experience of anti-ram bollards through my line of work. These bollards are just cosmetic. They wouldn't stop a goods vehicle of any description from "plunging" anywhere if it had a good run at them. It would be entirely possible for a determined goods vehicle to plunge itself off of GIV bridge if it aimed just right.

    I'm presuming that they're not there to stop an out of control lorry, but rather to stop one parking with two wheels up on the pavement, which could then give way under it, as the pavement is not designed for such weights.
