The Barnstaple Western Bypass is a congestion-relief scheme designed to take road traffic away from the town centre of Barnstaple, a market town in Devon, South West England. Construction of the new road started in the Spring of 2005 and it was opened on 23 May 2007. ==History== The scheme consists of a single two lane carriageway, one roundabout and three traffic-signalled controlled junctions. of new road was constructed and a long, five-span, downstream bridge was built across the River Taw. A new roundabout has been created between the Newport and Roundswell roundabouts with a feeder lane from the Roundswell side to the new two lane carriageway. This allows easy access from the A39 Atlantic Highway to the A361 Braunton Road which generates much of Barnstaple's traffic. The bridge is a balanced cantilever design with reinforced concrete box girders supporting the arms. Other constructions include stream culverts, two pedestrian/cycleway underpasses, minor retaining walls, and a 100-metre three span viaduct providing access for buses, cyclists and pedestrians to Barnstaple railway station. Also built into the plans was the ability to reopen the Barnstaple-Bideford railway in the future should this become financially viable. As with any project of this scale, many companies were employed in the development. Edmund Nuttall Ltd., a major civil engineering group, was the main contractor. It was estimated to cost £42 million. £38 million of this amount came from the central government. Devon County Council also contributed. An economic impact study was made and it was estimated that after 5 years the project would generate an extra £248 million in business turnover and would create 1,280 jobs. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Barnstaple Western Bypass」の詳細全文を読む スポンサード リンク
