Moulsford Railway Bridge (1839)

Moulsford Railway Bridge, also known locally as "Four Arches" bridge, is a pair of parallel bridges located a little to the north of Moulsford and South Stoke in Oxfordshire, UK. It carries the Great Western Main Line from Paddington, London to Wales and the West across the River Thames. The bridge lies between the stations at Goring & Streatley and Cholsey, and crosses the Thames at an oblique angle on the reach between Cleeve Lock and Benson Lock.

The original Moulsford Railway Bridge was built between 1838 and 1840, having been designed by Isambard Kingdom Brunel for the main trunk route of the Great Western Railway. Built to carry a pair of broad gauge tracks across the Thames, it consists of four low semi-elliptical arches spanning the Thames at a considerably skewed angle of 60 degrees.
