Here we go, bridge by bridge:
Bridge 1, Broadway
The last and toughest part of the major works – the removal of the two riveted plates from the Evesham side outer main girder - has been completed.
Removed lower flange from the Evesham side. This was the tough one! |

The old plates will be going back
to the workshops this weekend, to act as templates for the manufacture of new
plates. Bolting up of the similar new plates on the Broadway side is about 50%
completed, as you can see in the picture above.
The cutting out of the 19
corroded areas of deck plates will be completed today. The new workshop
made plates will be tacked into place, for safety reasons,
by tomorrow night. These will all be fully profile welded next week.
The corroded sections of all
of the outer joggled stiffeners have been cut away (see photo of the typical
corrosion result in the previous post), and most of those on the Broadway side girder have been welded
and bolted back into place.
Work on straightening and
repairing the impact damage on the minor members is also in progress.

A couple of historical items from this 1904 bridge:
A rivet from the Evesham side main girder |
The picture above shows how rivets were removed that refused to yield to a 20 ton press - they were drilled out using a hollow bit. There was quite a sense of achievement on site today, now that this flange plate is off. It proved a tough nut to crack, but we got there.
Bridge 3, Pry Lane
Brick repairs and pointing
are virtually complete to this bridge.
Bridge 5, Little Buckland
Excavation of the ground
behind the north abutment, down to the level of the original abutment
foundations, is now completed. Resin anchored dowel bars, to tie the new
concrete to the old abutment brickwork, have been installed. All excavation is
now complete at this bridge.
The full extent of the crack between
the downside wing wall and the Broadway abutment, which we believe moved forwards about
the time the bridge was first built, is now clearly exposed.
Shuttering
is being installed behind the Cheltenham end abutment ready for the second
concrete pour:

Low level shuttering is being installed on the line
of the replacement wing wall on the upside, Broadway end, to form the stepped
base of the new wing wall foundations. A combined concrete pour of the lowest
section of concrete behind the Broadway end abutment and this wing wall,
together with the Cheltenham end abutment pour 2, is planned for Monday next. This means a lot of concrete has to be bought!
You can see where the money is being spent, but the share issue is not yet fully subscribed. We are still £42.000 short. Please help if you can. Just fill in a form, send it with a cheque, and claim back 30% from HMRC. It works !
