It was authorised by an Act of Parliament in 1864 and construction of the 20 miles (32 km) long line was begun, but not completed.
To counter this threat, the LBSCR proposed to build a 20 miles (32 km) long railway linking Haywards Heath, Uckfield, and Hailsham.
From there it would follow the Ouse Valley to Sheffield Park and then pass north of Newick to Shortbridge and connect with the railway south of Uckfield, which was then the terminus of the line from Lewes.
Skew Bridge across Borde Hill Lane between Haywards Heath and Balcombe (TQ 325 273) has extended abutments where the railway would have passed over the road.
Although reported as destroyed during the construction of the Uckfield Bypass in the 1990s, the bridge is still in position although in decrepit state, visited but not photographed September 2009.
