    The news this morning is that the motorway will reopen at 0400 tomorrow morning - 24 hours early.

    That's pretty good going, no doubt helped by perfect weather conditions
    as there has been no rain since 21 December.

    Perhaps there will eventually be a time-lapse video of the whole thing.

    Congratulations to all concerned.

    A full timelapse would be interesting, but I suspect for most people,
    the interest would be the new span being slid into space, rather than
    the earth moving before and after,

    a bit of both, the green machines were gripping onto the 'bundles' of

    More obvious on their first test move ><https://vimeo.com/1148887679/eceef9bf9c?share=copy&fl=sv&fe=ci>

    I think those are what are generally called "Strand Jacks", often
    used for heavy lifting or moving.

    Quite possibly, searching for that term seems to show them commonly used vertically for lifting, but no reason against using them horizontally
    for pulling ...

    Called tendon jacks when I was in the civil engineering world, only for pulling though, pushing/compressing too easily goes off axis.
