In 1824, George Stephenson
was appointed as principal engineer for the proposed new railway line to be
built from Liverpool to Manchester. It was impossible to divert the turnpike
road or to realign the route of the railway at the crossing point, so the road
bridge had to be constructed over the railway line at an angle of 34 degrees.
The arch of the bridge was constructed of specially-shaped sandstone blocks.
The cost was £3735.
Robert Stephenson, George's son built the Rocket steam locomotive which won the prize at the Rainhill Trials held in 1829.
