    I thought that any newly installed bridges either had to be partially open (e.g the transfer deck at reading) or have an HVAC system to regulate the temperature. I used the new bridge at Strood last weekend, which is fully enclosed and was rather unsurprisingly, like an oven (I've never been quite so glad to see a lift arrive...)

    I'm now rather curious, is my understanding of the rules for new bridges wrong, or is there a loophole in the rules that allows the bridge at Strood to be fully enclosed that doesn't apply to other bridges, or should there be open windows in the Strood bridge?

    If anyone knows the answer I'd be very grateful.

    Where does it say that "closed" bridges have to have HVAC?

    Quite possibly nowhere and I've got confused - that's why I asked...

    Oh, I've always wondered why the newish bridge at Staines is partially open - especially since the wind blows the rain in and makes it rather slippery!

    Slough's old bridge is like an oven.

    I think what came up in an earlier discussion was that if a footbridge was fully enclosed it was treated as a different type of space in terms of fire precautions, and emergency escape capability etc etc.

    So it's a case of if enclosed then such and such must be done, but not 'must be enclosed'...

    Then there's designs like the bridge at Hyndland - double glazed windows to keep it it warm in winter, which can be opened if it gets too hot. No roof though.

    There will also be issues, likely involving union representation, if TOC staff are positioned on a bridge or other structure for ticket checks or other operation reasons and they consider the temperature to be too high or too low.
