Lo Wu Bridge, Railway bridge in Shenzhen, China.

Lo Wu Bridge is a railway bridge with a steel truss structure that spans the Sham Chun River. It carries trains between the railway networks of Shenzhen and Hong Kong, serving both passengers and freight.

The original railway bridge was built starting in 1906 and opened in 1910 as part of the British Section of the Kowloon-Canton Railway. The structure was later relocated downstream to allow for modern expansion of rail traffic.

The bridge's name comes from the Lo Wu area it crosses, and for decades it was the main foot crossing between Hong Kong and mainland China. Until the 1979 resumption of through trains, approved travellers crossed on foot, and a separate pedestrian bridge opened in 1985. Today the enclosed two-storey walkway carries pedestrians between Lo Wu station and Luohu station.

Pedestrians cross the border on an enclosed two-storey walkway, separate from the rail tracks, so no one walks over the rails. The 1985 partially covered walkway and an older truss footbridge were replaced by this structure. The preserved 1957 truss span stands on the Sham Chun River bank beside Lo Wu station, downstream of the working bridge.

The 1957 second-generation bridge, 32 metres long, was moved in September 2003 to a site beside Lo Wu station and kept as a monument. Moving the whole span across the live railway line was the hardest part of the operation.
