width = Opened to traffic on 28 February 1934 by the Duke of York, the Tees Newport Bridge spans the River Tees a short distance upriver from Middlesbrough Transporter Bridge, linking Middlesbrough with the borough of Stockton-on-Tees, England. Designed by Mott, Hay and Anderson [Richards, James M.: "The National Trust Book of Bridges", Butler & Tanner Ltd., 1984, p. 177] and built by local company Dorman Long, who have also been responsible for such structures as the Tyne Bridge and Sydney Harbour Bridge, it was the first large vertical lift bridge in Britain. [Rennison, R.W.: "Civil Engineering Heritage: Northern England", Thomas Telford Publishing, 1996, p. 91]

Constructed around twin 182ft (55m) lifting towers, the 270ft (82m) bridge span, weighing 2,700 tonnes, could be lifted by the use of two 325 H.P. electric motors at 52ft per minute to a maximum height of 120ft (37m). In the event of motor failure a standby 450 H.P. petrol engine could be employed to move the bridge, but should both systems fail it was possible to raise or lower the span manually using a winch mechanism. It was estimated in 1963 by Mr R. Batty, long time Bridge Master at Newport Bridge, that "it would take 12 men eight hours" to complete the movement by hand.

Originally 12 men would have been employed to man the bridge around the clock, usually requiring four to drive it at any one time. This was accomplished from the oak-panelled winding house situated midway along the bridge span. During the 1940s and early 1950s this would occur up to twice a day, however, as the number of ships needing to sail up to Stockton-on-Tees declined, so did the usage of the bridge.

With the planned construction of the Tees Barrage heavy river traffic all but ceased and the decision was taken to seal the lifting span. The bridge was ceremoniously raised and lowered for the last time in an informal ceremony on the 18th November 1990, this time with scores of people enjoying the ride. The span was subsequently bolted down.

Tees Newport Bridge still serves as a road bridge, carrying considerable traffic as a section of the A1032, despite the presence of the A19 Tees Flyover a short distance upriver. In recent years it was repainted in its original green and some minor maintenance took place on the wire ropes and counterbalances which still take the majority of the bridge load.
