High Level Bridge Over The River Tyne - Sub Surface Drainage
The High Level Bridge, built by Robert Stephenson over a three year period, spans 1337 feet over the River Tyne in Newcastle. The bridge was built for the York, Newcastle and Berwick Railway and was opened to rail traffic on 15th August 1849, but was officially opened on 27th September the same year by Queen Victoria. Over the years many additions have been made to the bridge, such as a single carriage way road and pedestrian walkways. The total weight
of the structure is now 5,000 tonnes.
In 2001, to ensure the long term future of the bridge, specialist contractor May Gurney was appointed by Gateshead County Council to identify aspects of the bridge that required repair. The commencement of restoration revealed that the 160 year old bridge was in worse wear than was originally anticipated. 610 tonnes of steel and 252 tonnes of timber were used in the restoration of this grade 1 listed bridge. The bridge was closed to road traffic at the beginning of 2005 so that repair work could begin on the badly cracked iron girders and timber deck.
Job Brief
Background Information
Project Team
Client: Gateshead County Council
Main Contractor: May Gurney
Sub Contractor: Ekspan Ltd
Start Date: 2005
Completion Date: 7 July 2008
Ekspan was approached by May Gurney for a drainage solution. We proposed our 325 drainage channel paired with our 302/51 through deck system. Ekspan provided a number of pipe connections to ensure that the pipework could pass through the intricate wood and iron structure allowing the sub surface water to drain away quickly and efficiently. Using both the 325 and 302/51 system to channel the water in this way ensures the life of the structure is further prolonged. At only 35mm high the galvanised steel 325 section is easily grouted to the deck. The 325 is also easily connected to the 302/51 through deck system by use of a 325 T outlet. If you have any queries or require further details on how the 300 series could benefit your structure our sales team will be more than happy to assist.
