"...where the Tees ambles its way through the watermeadows in a series of loops and 'S' bends, nearly doubling back on itself around the Sockburn Peninsula, a strangely remote place to find near the perimeter of a busy airport and wihin a dozen miles of the huge Teesside conurbation."
The Companion Guide to Northumbria. Edward Grierson. 1976
Yarm is a nice old town, and leaving it behind the Tees begins a series of meanders through rural surroundings with some small isolated footbridges and a few road bridges until reaching the village of Hurworth and nearby Croft linked by a 15th century road bridge and a Victorian railway bridge. Passing just south of Darlington, the river is crossed by major bridges at Blackwell and Low Coniscliffe, thence to Piercebridge and another old bridge some forty miles from the source of the Tees.
The river Tees forms the boundary between County Durham and North Yorkshire along much of its length from near Yarm to beyond Piercebridge.
