Original features

The spectacular 450-tonne Infinity Bridge over the river at Stockton-on-Tees officially opens this week.

Built for £15 million, it links the major North Shore waterfront development with Durham University's Queen's Campus and the Teesdale Business Park.

Its two flowing arches, when reflected in the water, form the mathematical symbol for infinity. Spanning a total of 180 metres and, at the highest point, reaching 40 metres above the Tees, the footbridge is one of the longest in the UK.

The underfoot and handrail lighting is environmentally friendly and creates a dramatic nightscape, as well as ensuring a safe and pleasant crossing for the 4,000 people who are expected to use it each day.

The bridge, which was built by Tees Valley Regeneration and Stockton Borough Council, and designed by Expedition Engineering and Spence Associates, will also facilitate Durham's expansion.

Almost 2,000 of its 15,000 students are currently based at the Queen's Campus and they will now have easy access to the residential, commercial, medical, hotel and leisure facilities being created across the river on North Shore.

The university has also purchased an option on four acres of land there, which it may use for a new residential college, a conference centre and research projects.
