Broom Bridge, Southill
This crossed a channel of the River Ivel which forms the boundary between Southill and Biggleswade. A brick bridge was replaced in 1823 with an iron bridge designed by John Millington, the County Surveyor. The ironwork was made by Lees Cottam and Co of Coalbrookdale. The bridge had a simple single span of 20 feet. On 18th February 1873, a traction fell through the arch, all but destroying the bridge.[1]
