The first estate programme began with the building of the council-owned Cyprus Estate which has since been complemented by other private housing schemes such as Fairfields and Ollands built mainly in the 1970s and a large estate on the south side of the town in the 1990s. The traditional traffic route along the A11 trunk road became a bottleneck as it ran both ways along High Street and Church Street, thus in the 1970s a one-way system was opened channelling traffic around the natural ring road surrounding the church. The volume of traffic continued to increase making that change obsolete so the Attleborough bypass was opened in 1984. The bypass was widened and completed in 2007 removing the only single lane section of the A11 between Thetford and Norwich.
