The Newbattle Viaduct, sometimes also called the Lothianbridge, Newtongrange or Dalhousie Viaduct, carries the Borders Railway, which opened in 2015, over the River South Esk near Newtongrange, Midlothian, Scotland.

The original viaduct was built by the Marquess of Lothian to extend the Edinburgh and Dalkeith Railway from Dalhousie Mains to his coal pits at Arniston.

[1][2] It was constructed of stone piers to support the wooden structure of the bridge, and had a total length of around 1,200 feet (370 m).

[1][5] Some work was required on the viaduct to prepare it for the reopening of the railway, although it was still structurally sound.

[8] The viaduct is nearly straight, but with a slight curve at the northern end where it crosses the river.
