Summary
[edit]DescriptionTraeth Mawr Viaduct IMG 3510c copy.jpg |
English: The Dovey Junction to Pwllheli railway crosses the River Glaslyn over Traeth Mawr just outside Porthmadog. The structure was built before the opening of the railway in 1867 and was originally 40-plus spans but was significantly altered over the years to its present day 16 spans.
Although Traeth Mawr is Barmouth Viaducts’ little sister, this in no way made it easier to deliver. In fact, due to the river Glaslyn flood plain being artificially altered when Porthmadog Cob was built, what was previously a normal estuary is now a complex area subject to flooding and tidal influences. Traeth Mawr timber trestle railway viaduct was originally built by the Aberystwyth and Welsh Coast Railway, and the section opened to Pwllheli in 1867. Benjamin Piercy and Henry Conybeare were the engineers who also designed Barmouth and the other timber viaducts on the route – Thomas Savin from Oswestry was the contractor which built the viaducts.
