Longhill Viaduct

Longhill Viaduct
Longhill Viaduct was originally constructed in 2005, using concrete supports and other reclaimed material. This incarnation of the bridge was heavily used until it was demolished in 2013 to make way for a building extension.

In 2014, the new bridge was finally completed along with 2 new lifting sections for pedestrian traffic either side of the new building extension. The extension itself was constructed over the site of the old bridge, and as a result the track alignment had to differ to reach the new spans which now traverse though the house. The new spans were constructed using wooden decking and supports and are able to be removed if necessary. The track was bought in as new for the relaying effort, as well as some renewals elsewhere on the line.

Part of this project included new wiring looms being installed for signalling efforts on the Longhill Tunnel end of the viaduct, and included construction of a new Advance Starting signal and track circuiting for the Worgret Junction section, enabling trains to use the bridge for shunting around Winfrith Newburgh without requiring a single line release.
