 The metropolitan boroughs of the City of Salford and the City of Manchester border Trafford to the north and east respectively; the Cheshire East area of Cheshire lies to the south. The geology of South Trafford is Keuper marl with some Keuper waterstone and sandstone, whilst the geology of North Trafford is Bunter sandstone. The River Mersey runs east to west through the area, separating North Trafford from South Trafford; other rivers in Trafford include the Bollin, the River Irwell, Sinderland Brook, and Crofts Bank Brook. The Bridgewater Canal, opened in 1761 and completed in 1776, follows a course through Trafford roughly north to south and passes through Stretford, Sale, and Altrincham. The Manchester Ship Canal, opened in 1894, forms part of Trafford's northern and western boundaries with Salford.
