I have spent the last week sieving through a lot of online information about the Castlefield Viaduct, I have also looked into the Bridgewater Viaduct and have more recently been directed towards another named bridge, the Great Northern Railway Viaduct. It seems to be very difficult to distinguish exactly what the official name for the bridge is, as there are four bridges which are built next to and around the same area. As a result this is having a knock on negative and unsuccessful affect on my research into the history of this abandoned viaduct. without this it is impossible to narrow the information online, at the museums, library or Archive stores. It has been a really frustrating week as I feel I have not a lot to show for the amount of time I have spent searching. I will however include the emails and notes I have made from the phone conversations in my work file.
