Are scenes like this on the way to Shropshire and Mid Wales?

This abnormal load caused delays for motorists as they negotiated tough corners on the A483 trunk road at Chirk, near Oswestry, earlier this week.

It comes just weeks before lorries carrying wind turbine parts come to Mid Wales – first for a test run next week and then the real thing during July.

Delyth Jones, of North Wales Police, said: "We notified the public on Twitter that the turbines were being transported to Ty Nant at Corwen at 9.15am, 12.30pm and 3pm on Monday and Wednesday.

"They went past the Gledrid services, near Oswestry, and there were no major problems on Monday – it obviously depends on traffic flow – and we try to give the public warning as soon as we know about these loads. We usually receive a notice of abnormal loads just a few days in advance. If the public would like to know if more of the loads are expected, they can follow us on Twitter: @NWPolice." The transporters, which will take turbine parts to a windfarm in Mid Wales, will begin their journeys along the A483 at the start of the summer holidays.

A trial run of a convoy, minus the turbine parts, will take place on June 30 and the actual deliveries will start on July 25.

Each convoy will enter Shropshire from the Chirk bypass, travel along the Oswestry bypass then on to single carriageway roads through Pant and Llanymynech.

They will arrive in Welshpool around noon and are expected to take about 15 minutes between Rhallt Lane and Raven Street depending on traffic conditions. "They will arrive in Welshpool shortly after noon and take about 15 minutes between Rhallt Lane and Raven Street depending on traffic conditions," Sophy Fearnley-Whittingstall, for Awel Newydd, said.

"We have planned for one delivery per day up to six days a week, which would take approximately two months. We are aiming to shorten this, by increasing both the frequency – to two deliveries – and size of the deliveries to three abnormal load vehicles, subject to the police deeming it is safe."
