But what do you do with 4420 tons of demolished arch? The chief contractor responsible for smashing the arch to bits was called Frank Valori, and he managed to find two particularly interesting hiding places for the dismembered stonework. One of these was his own back garden (at "Paradise Villa" in Kent) where a row of stones was used to create a fetching (and very cheap) terraced rockery. The other, rather more considerable, dumping ground was in Bromley-by-Bow in East London. British Waterways had problems with a scoured-out riverbed that needed infilling, so roughly 60% of the Euston Arch was dumped into the tidal waters of the Prescott Channel. And, hurrah, yesterday they started lifting the stones back out.

More recently the Prescott Channel has been the site of major Olympic development. In order to bring building materials into the Park by boat, a set of enormous lock gates is being constructed to stabilise water levels upstream. It's meant the temporary sealing off of three local footpaths, and the permanent demolition of Davina's Bridge, but the outcome might just be ecologically worthwhile.
[I wrote a long post about the new lock and the old Big Brother house here, so I won't repeat it all today]

Blimey it's taking a very long time to build the new Prescott Lock - considerably longer than originally planned. Construction began in March 2007 and was due to be completed "in summer 2008 in time for the main construction phase of the Olympic Park." Nope. The deadline later slipped to "autumn 2008", with landscaping of the surrounding riverbanks to be complete by "February 2009". Failed, on both counts. There's still a sprawling worksite on Three Mills Green, sealed off behind an unwelcoming wall, and there's no sign that anyone's even close to prettifying the scenery or re-laying turf. All three footpaths are still closed off, no longer with visible signs to indicate diversions nor anything to suggest when these riverbanks might reopen. At the moment they're still at the "dredging the river" stage, and this explains why the Euston Arch is finally being exhumed.

Hurrah for the London Olympics, because without their sustainable transport policy the remains of the Euston Arch would have been doomed to a forgotten underwater life. As it is, this grand gateway may yet be reborn beside the Euston Road, where it ought to look bloody marvellous. One day.
