The Tees Transporter Bridge connects Middlesbrough and Port Clarence carrying the A178 road from Middlesbrough to Hartlepool via a travelling 'car' or 'gondola' suspended from the bridge by steel cables across the river. Constructed by Sir William Arrol & Co. of Glasgow between 1910 and 1911 it was opened by Prince Arthur of Connaught on 17 October 1911. The bridge was given Grade II* Listed Building status in 1985.

It has an overall length of 259.3m with a centre span of 173.6m and the beam of the bridge is carried at a height of 48.7 metres above the River Tees. It is the second longest of around eleven surviving structures of this type amongst only twenty ever built around the world. The bridge remains fully operational and provides a regular quarter-hourly service 18 hours a day.

The owners of the bridge, Middlesbrough Council and Stockton-on-Tees Borough Council, are planning a major refurbishment of the bridge in time for the Centenary in 2011.

The CIHT North Eastern Branch will join other institutions in marking the Centenary with a programme of events. Further details will be added here as they become finalised.
