Two giant transformers, each weighing 89 tonnes, will cause “minor delays” on roads as they are transported through Perth and Kinross.
Scottish Hydro Electric (SHE) Transmission have finalised plans to arrange delivery of the large units which are needed as part of the £600m Beauly to Denny power line.
A specialist haulier has been employed to ensure the safe delivery of the two mammoth transformers as they make their way from Bristol docks to Braco in Perthshire.
A spokesman for SHE said there will be “minor delays” on Perthshire roads but the contractors, Alley Heavy Haulage, will ensure this is kept to an “absolute minimum” when they make their way to Braco on October 6 and 9, in two separate journeys.
“There will be a private escort after talks with the police, but the route will be pretty straightforward,” he said.
Keith Inglis, SHE transmission project manager, said: “Both transformers were constructed in Porto, Portugal, and have been shipped to the docks at Bristol. We have employed an industry specialist to complete the last leg of the journey by road using a highly technical transport system.
“Due to the transformers’ dense weight and size, there is requirement to use a 30m long, seven-axle multi-steer trailer for each transformer that can be manipulated to manoeuvre around obstacles.
“Due to the nature and size of the delivery it will be escorted throughout the journey to ensure the safety of members of public.”
The Beauly to Denny line will carry renewable energy generated in the Highlands to central Scotland. It was given the green light by the Scottish Government in January 2010 despite opposition from campaigners who claimed it would destroy scenic areas and damage tourism.
The power line has led to 600 new towers being built with the whole project expected to be completed this year at an estimated cost of £600m.
