See TQ3193 : The New River between Highfield Road and Carpenter Gardens, N21 (2). Shows the location of TQ3294 : Hoist by the New River north of Ridge Avenue, N21.

For most of its original course, the New River followed the contours of the land up the valleys of the small tributaries of the River Lea (or Lee), resulting in many loops to the west and back again - see for example TQ2992 : The former course of the New River in Arnos Park.

At Salmon’s Brook in Bush Hill, the valley was quite narrow, and a wooden trough, 5 ft wide, 5 ft deep, and over 200 yards long, was built to cross it, supported on wooden arches up to 24 ft high. A bridge was built over the brook; this was replaced by an arch in 1682 when the Earl of Clarendon was Governor of the New River Company. The timber frame was raised by 1 ft in 1725.

Over 170 years later, in the mid-1780s, Robert Mylne replaced the trough with the clay-lined earth embankment shown in this photo.
