HWH - the Blue Bridge
29 Oct 2024 |
|
The iron "Blue Bridge" across the River South Tyne in Haltwhistle was pedestrianised in 1972, but was once a major crossing point. Originally built in 1875, it received a major overhaul in 2003.
The river is in high winter flow, almost spate conditions.

Outside KillFrost, looking downstream towards image17of18 - this area of the bank is being eroded.

This is about halfway between the viaduct and the river flow meter site

A series of 18 images showing erosion and penetrations of the concrete cap, which has allowed scouring of the underlying fill leading to some significant voids and un-supported areas.

Some of the larger rocks in this deposit look like rock armour that has been relocated downstream by floodwater.

Note also that the slabs built into the bank in the background [which has been damaged].

The void under the concrete extends far enough upstream [ie leftwards] to be in line with the viaduct pier. [Camera is about a third of the way in on the next pier - Skew viaduct].

Looks suspiciously like a drill hole ! {i'm comparing it to the capped off holes that were used when the "Old Quay" at Whitehaven was grouted, to stabilise the structure.
[shoe is about 100mm across at the widest point].

All but the upper section, which was held together by the concrete capping, has been removed by the scouring action of floodwater [yes, looking upwards !]

Looking downstream from inside the largest hole, also visible are the destroyed gabions & other steel reinforcement. [rather dangerous, IMO]

"inside" the largest hole !
That puddle is about 18" - 2ft deeper than the point the ranging pole reached ...

There is a low section along there - another couple of inches height and the river will be over the lip of this mini-weir.

That is a 5ft section of a surveyor's ranging pole, that's not the deepest point. But five feet is about average overall.
It's a big hole ... estimate 15' x 15' and 5' deep - although it's not square in plan.
