ORGANISERS of the Westbury chimney demolition are advising people not to stop along the B3098 to watch the spectacle.

The 400ft chimney will be brought down using 216 charges packed with nitroglycerine at 7am on Sunday morning.

A one-way traffic restriction will apply to Newtown / Long River Road westbound from its junction with B3098 Bratton Road for its entire length and Portway / Castle Road, Bratton westbound only from Wicklands Down Car Park to its junction with B3098 Westbury Road.

Restrictions will be clearly indicated by traffic signs and it is expected to last between 5am and 8.30am.

Organisers are recommending that people allow enough time for their journey to the site and to arrive before 6:45am.

Jonathan Toyn, senior estates manager at Tarmac, the company which owns the site, said: "This event really will mark the end of an era.

"The cement works have been in Westbury for over 50 years and lots of people see the chimney as an iconic landmark in the local landscape."

Wiltshire Police will have a presence on the day to support the safe running of the demolition, working mainly around the safe access areas and road closures, along with Westbury Lions.

There will be no toilet or refreshment services provided for the viewing and overnight camping, as well as use of disposable barbecues, is not permitted.

People who want to take photographs or video the demolition will be able to do so but the use of drones is not permitted unless authorisation has been approved.

Network Rail will carry out an inspection of the nearby railway track after the blast to ensure that trains are safe to run.

The weather forecast is currently predicting cloud with sunny intervals on Sunday morning, so the demolition is expected to go ahead.
