A report from John, our structures engineer at 16.00 today:
Bridge 5, Little Buckland
Excavation has re-started on the Broadway end. The section of this under the upside, Broadway end wing wall will be deeper, as the old foundations have to come out since they have failed. The digging has exposed a very nasty crack at the junction of the wing wall and the back of the abutment (see below), which is likely to be linked to the earlier reported crack on the face (50mm wide at the worst point). As can be seen it is also undermining the support to the padstone carrying the end of the outer main girder. It is hoped that the lowest concrete pour can be placed early next week.
Crack behind the wing wall, and underneath the pad stone |
The bricklayers have completed a couple of awkward bits including the return on the upside Broadway end abutment corner (see below). This will be connected to the new wing wall when it is re-built. Then the new pilaster will be built on top of the completed wall.

The steelworkers have started
re-fitting the two new blast cleaned shiny plates to the underside of the
downside outer girder. On the 3 pictures below you can see there are loads of
22mm high strength bolts to be installed. They are also cutting out some of the
damaged areas on the lower flange of the upside outer beam. (i.e. on the other, Evesham side, also hit by lorries)
Newly fabricated flange plates being installed |
The painter has been very
busy, below deck as well, and has the first of two top coats on about 75% of the
steel. The bricklayers have installed a foundation for the upside, Cheltenham
end pilasters and were working on the plinth brickwork. This pilaster had fallen over (or was it pushed!)
Then an amazing thing happened at the southern end of platform 2 at Broadway: S&T installed a tall viewing platform, just for us ! This enables us to reveal to our faithful readers this exclusive and as yet unique view of the Broadway bridge works from above:
Prominent are the three brown painted main girders, and the orange decking in its undercoat before water proofing.
A close up shows our structures engineer John, in the company of the bridge contractors, watching the new flange plates being manoeuvered under the bridge.
And what was this new viewing platform by the bridge? Why, it's the new bracket signal ! As if you hadn't guessed... Doesn't it look good, now that it's fully assembled!
With thanks to Andy P, our roving S&T reporter.
Stunning progress, you cannot fail to be moved by the effort put in by all concerned, thank you.
