A single-span skew underbridge over the River Amber, built c.1837–1840 to the design of North Midland Railway Assistant Engineer Frederick Swanwick, under George and Robert Stephenson, and widened on both sides c.1863–1880. Crich Junction Bridge is listed at Grade II as an early example of a railway structure dating from the pioneering phase in national railway development. The bridge forms part of the North Midland Railway, a railway line designed by George and Robert Stephenson, among the greatest and most influential of all railway engineers, with their assistant Frederick Swanwick. It is as an example of the consistently high quality design and careful detailing of railway structures completed for the North Midland Railway. Although widened in c.1863-1880, the alterations, as they stand, closely match the existing structure and are of interest in accommodating a major Midland Railway junction. It is one of the earliest types of railway skew-arched bridges in the world built according to the ‘helicoidal’ system of construction. With a series of listed railway structures at Ambergate and Bullbridge that share a common architectural language, Crich Junction Bridge forms part of a historic railway landscape of great interest.
