aerial photograph of Penwortham Old Bridge over the River Ribble at Preston Lancahsire. Grade II listed Penwortham Old Bridge was built in 1759 and replaced a previous bridge which collapsed in 1755. Behind are the remains of the West Lancashire Railway Bridge built in 1881. The bridge carried the line to Southport. In 1925 a gas pipe was added to the structure so when the railway was closed in 1965 the piers were left in place to keep the gas pipeline in service.
