In 1833, Brunel was made chief engineer of the Great Western Railway, and he created a broad-gauge track that was seven feet wide. Not only could the wheels be accommodated in this fashion, but it also became possible to carry passengers. Brunel is perhaps best remembered for designing the Clifton Suspension Bridge in Bristol. Spanning over 700 ft. (210 m), and nominally 200 ft. (61 m) above the River Avon, it was the longest bridge in the world at the time of construction. Besides he improved the design for the bridge over the Tamar river near Plymouth.
