The viaduct is said to be one of the largest brick-built structures in Britain and is a Grade II listed structure. More than 6 million bricks were used in its construction! It was completed in 1849 and is a rail line connecting Marks Tey to Sudbury. The viaduct is a total length of 1066ft, consists of 32 arches and is 75ft tall at its highest point.
Underneath the viaduct is a play area, together with the Millennium Green. One area of the Millennium Green is a ‘Public Recreation’ field, part of it is a big green field, and the other section is a wildlife area, with a wide range of plants and trees, many are newly planted. The second area is the ‘Water Meadow Nature Reserve’. A boardwalk goes around the perimeter of the reserve. There’s also a small pond and lake.
