The first Cross Keys Bridge was replaced in autumn 1850 by one designed by Robert Stephenson. The second bridge was of cast and wrought iron, and crossed the river c.100ft south of the previous one. According to the Stamford Mercury of 6th October 1850, the moveable section, about 126ft long and pivotted on the east pier, weighed about 80 tons and was to be turned by a crank operated by one man. A second toll house was built which survives as a private house. When the railway from Spalding was extended to Kings Lynn in 1864, the company bought the road bridge and used the southern half for their line. {1}{2}{3}
