Garretts of Leiston are well known for making steam engines but they also made other artefacts, including iron bridges and at least one of these survives.
It is in the village of Thurlow, Sufolk, about three miles from where steam rallies are held and during the millenium year the EATEC organised a small steam road run from the rally field to the bridge and back. This was to celebrate the 150th anniversary of the bridge's construction and was run on August 5th, 2000.
Of the five engines that took part, four were made by Garretts, the exception being Allan Marchington's 1911 Fowler 'Titan', Works No. 12226, which carries a plate stating that it weighs 14 tons.
Although the weight sign at the bridge is 6T, prior information from locals had been given to the engine drivers that loads of twice that, or more, were consistently taken over it. Allan, therefore, had no hesitation in driving his heavy Road Loco. over the bridge and back again.
The four Garrett engines were:
'British Hero', Works No. 27160, owned by Bruce Whately and Charles Saunders, built in 1908 and believed to be the only surviving Garrett Showmans Road Locomotive.
'Adventurer' a 1918 Steam Tractor, Works No. 33296, owned by Molly and Mike Dyson.
'Evelyn' a 1924 Steam Tractor, Works No. 34539, owned by Eve Nevard.
'Felsted Belle' a 1916 Traction Engine, Works No. 32936, owned by David Nourse.
The bridge was, therefore, fully tested by these five engines, plus a 1904 Stanley Steam Car. Being of cast beam and steel plate construction on two main girders, perhaps it will still be standing in another 150 years!
