BRIDGE 09 – AQUEDUCT/ PEDESTRIAN FOOTBRIDGE – FINAL REPORT
The Aqueduct/footbridge is now totally completed and the Public Footpath which it carries has now been re-opened.
You can just about make out the timber fencing at each end on the south view photo.

The main changes, since the last report, are to the east (Cotswold) bank seat.

This has been enlarged to provide a better entrance, with a new “landing” area.
|New timber fencing, here on the Malvern side|
All of the timber fencing around the Public footpath approach section at both ends has been replaced.
The inlet on the Cotswold side has been fitted with a grating. This end is now fixed so the joint between the steel box and the concrete approach channel should no longer leak.
The final (not very clear) photo is of the Malvern end showing the rollers which retain the steel box but allow for movement due to expansion, which could total up to 25mm over the likely temperature range encountered in this country (minus 10 C to + 35 C).
Heat absorption by the steel can add another 5C.
Inevitably, when working in November/December, there were a few problems encountered during the works:–
- Low temperatures slowing the off-site painting operation and some of the brick laying.
- The gales, which stopped the expensive 60T crane from being used for the steel erection work. Although excellent service using a large lorry with a very long reach Hiab crane was substituted, this was nowhere near as flexible. It involved some shunting of the lorry to and fro between lifts, to optimise the reach and angle needed. The short notice availability and reach issues probably added about 2 days onto the installation operation.
- The rain, which made access up the embankment difficult and caused delays in excavation, concreting and brick laying, and the final making good.
Fortunately, by very hard work and chasing around for alternatives, the Contractors were able to overcome all of these issues, and managed to get the line cleared in time for the northbound Santa trains to start on Saturday 8th December, as originally programmed. The Contractors were finished just 2 days late, on the Tuesday night (11th) and finally cleared all their welfare and storage cabins, waste skip and plant site, from Stanton yard on Friday (14th) leaving it a lot clearer than before they started (photo)!
