Sandygate Roundabout, Exeter
Sandygate Roundabout, Exeter (Roads)
SWH began works to re-align the central island to Sandygate Roundabout at Junction 30 of the M5 in the spring of 2008.
The works involved widening the carriageway either side of the motorway over bridge and included clearance of wooded areas and major re-grading of embankments.
The storm drainage system was largely altered and existing services repositioned or replaced. Temporary traffic signals were maintained until the new, permanent signals could be installed.
Due to the extreme volumes of traffic using this junction, the majority of works were carried out at night. To ensure the safety of both members of the public and our workforce, we prepared and implemented a complex traffic management plan. The scope of works increased substantially during the contract due to the discovery of previously unrecorded services.
In May of 2010, SWH were instructed to carry out the remaining phases of work to complete the Sandygate scheme. Again the works have been carried out almost exclusively at night to minimise disruption to members of the public. These phases have involved major earthworks operations, diversions of stats services, widening of carriageways and alterations to traffic signals. In all, seven different on and off slips have been altered within the scope of phases 4 to 7. This scheme was undertaken for Devon County Council.
