A view of the underside of the Royal Tweed Bridge, which spans the River Tweed,...

The road bridge was designed by L. G. Mouchel and Partners, and was built 1925-28 by the Holloway Brothers with additional support from consulting engineers Colonel C. H. Bressey and Mr J. H. Bean. The 430m bridge has four arches, three of which cross the river, each with four ribs. There are columns rising from each rib to support the longitunal beams, which in turn support the perpendicular transverse beams which carry the road. The image shows the underside of the bridge, most likely from the east bank of the river, looking south-west, and two of the arches with ribs crossing the river. The reinforced concrete in the foreground shows some of the board-marks left by the moulds.
