The two-mile £3.8m Tarporley Bypass opened in September 1986. The A51 overlaps the A49. Tarporley Community High School is near here. The road leaves the A51 to the west at Four Lane Ends near the Red Fox. The road travels over the Shropshire Union Canal and under the Welsh Marches Line railway (to Hereford) south of Tiverton. It crosses over the River Gowy north of Bunbury next to the Beeston Castle (named after the real Beeston Castle to the west).
