Description
The Twerton Tunnel's west entrance, located on the south side of Lower Bristol Road and adjoining Carr's Wood, is a railway tunnel entrance built around 1840 by Isambard Kingdom Brunel. The structure features Lias walling with ashlar dressings in a Tudor style, characterized by a single four-centred arch with a dressed flush face set between forward abutments that have crenellated copings. The main parapet is topped with saddle back coping and includes a weathered string that spans the full width of the entrance. The lower parts of the walls flare out. This entrance is similar to the east entrance but lacks flanking turrets. It is part of the development of the Great Western Railway line between Bath and Bristol, which opened to traffic on 21st August 1840. The tunnel is 111 feet long and is known as No. 6 Tunnel by the railways. There is also a considerable retaining wall that is approximately 1,120 feet long and up to 49 feet high, connecting this tunnel with the Twerton Wood Tunnel.
