Shaldon Bridge, Teignmouth
Shaldon Bridge, Teignmouth (Structures)
This contract involved the renewal of Shaldon Bridge (which connects Teignmouth and Shaldon over the River Teign).
It also included demolishing the existing footways and construction of new steel columns.
The original lifting span was of steel and timber construction and was just 6m wide; the new span was fabricated steel section 7m wide plus two footways 1.5m wide and designed to take full HA and HB loadings. As the steel lifting girders were to be maintained along with the original lifting mechanism, the new section had to be of similar weight but strong enough to take the increased traffic loading.
The strengthening works consisted of removing the existing concrete edge slab and parapets and driving new tubular steel piles into the tidal river bed to support new wider combined footways and cycleways with parapets on both sides of the deck. The new superstructure construction was a reinforced concrete slab composite with steel plate girders supported on tubular steel columns that were a continuation of the new piles.
Other works included extensive concrete and steelwork repairs and waterproofing and resurfacing to the existing bridge superstructure, refurbishment of the lifting span, and widening a short length of the Teignmouth causeway adjacent to the lifting span.
We maintained traffic flow over the bridge, and installed the new span in two halves, bolting it together on completion. This scheme was completed for Devon County Council.
