The town's location at the intersection of the routes from London to Bristol and from Southampton to Birmingham made it, for many years, a transport bottleneck. In 1963 a Dual Carriageway was built east of the town centre to ease congestion and the opening of the M4 in 1971 moved the intersection of these major trunk routes three miles north of the town, to Chieveley. The ring road around the town still suffered serious congestion and the Newbury bypass was proposed in 1981. The plans were approved in 1990. However they were extremely controversial and this led to a major environmentalist campaign opposing the road development (dubbed the "Third Battle of Newbury" by parts of the national media). In spite of this, the road was built and finally opened in 1998. Within two months the road surface began to break up and the entire length of the bypass was eventually resurfaced over two weekends using an improved low-noise water-absorbent surface.
