Snippet Detail

The embankment immediately adjacent to (and to the south of) Bridge SAC/322 suffered a partial collapse in December 2015 following an extended period of particularly wet weather. As the embankment collapsed, it demolished part of the bridge's south-eastern wing wall.

Temporary repairs were made by Network Rail within a few days.

Permanent repairs were undertaken during the first quarter of 2017. (Eden District Council Planning Application Number 16/1069 relates to these works.) As part of the permanent repairs*:

  • a concrete culvert was constructed through the bridge arch (to allow surface water to drain from the western side of the embankment);
  • the two parapet walls were reduced in height;
  • the 'tunnel' (bridge arch) was infilled with 'foamed concrete';
  • the wingwalls were 'decommissioned'; and
  • the void was infilled with 'compacted class 6N fill'.

* Source: A pdf document submitted by Network Rail to Eden District Council as part of the planning process. At the time this document was reviewed, its filename was "16-1069 - Drawings.pdf".

In essence, the original bridge was entombed and completely hidden from view.

Bridge 322 lies within the Settle-Carlisle Railway Conservation Area. However, despite this, the Friends of the Settle-Carlisle Line were NOT consulted (by either Network Rail or Eden District Council) prior to these works being undertaken.
