Bishop Auckland's improved town centre will be unveiled this week after a £450,000 environmental programme.

The alterations in Newgate Street are the latest in a £750,000 package of measures to improve the appearance and vitality of the town.

Durham County Council, Wear Valley District Council, Bishop Auckland Town Centre Forum and regional development agency One NorthEast joined forces to carry out the 20-week scheme.

At noon on Friday, Bishop Auckland MP Derek Foster will unveil the improvements.

The opening will be followed by street entertainment.

Chris Tunstall, Durham County Council's director of environment and technical services, said: "The scheme has made a dramatic improvement to the centre of Bishop Auckland and is part of an overall regeneration for the town.

"Traders and shoppers have had to cope with a fair bit of disruption while the works have been taking place, but the difference to the appearance of the area really is remarkable."

The street has been re-paved and now has an improved pedestrian environment, defined disabled parking areas and loading bays.

Bus stops have high kerbs to permit easier access on to new low floor buses. Services will return to their normal route on Saturday after diversion during the work.

Mr Tunstall said: "The new street lighting is a first for County Durham.

"It uses white light in place of traditional yellow or sodium lamps, giving better illumination and improving safety. The columns are designed for hanging baskets and wired to take Christmas lights."

The work is part of a scheme which will see the new street lighting extended from Princes Street to the railway station traffic island.

Pedestrian safety and traffic management measures will be introduced in association with the Asda store development, to improve Newgate Street between Princes Way and Bob Hardisty Drive.

Public art is also a feature of street, with a series of decorative bollards and seating being installed.

Town centre manager Ken Wilson said: "The town has such a long association with bishops that the artwork reflects the town's history and strengthens its identity.

"The whole scheme will benefit the area, hopefully making it more enjoyable for visitors and, in turn, traders."
