The bridge in St Michael's Street, adjacent to Kingsbury Mill, dates from 1765 and is believed to be the oldest extant bridge in Hertfordshire. It is Grade II listed. According to a contemporary account of the Second Battle of St Albans in 1461, another bridge existed on this site previously (recorded in 1505 as "Pons de la Maltemyll" - Malt Mill Bridge). It is thought that the Romans had built a bridge here by the 3rd century AD. The ford alongside the current bridge, which is known to have existed for 2,000 years and is traditionally believed to be Alban's crossing point on his way to his execution, was substantially restored in 2001 by local residents' associations.
