Repair work has begun on power lines across the Lancaster district as park of a £30m National Grid project.
The company is upgrading a power line across Cumbria and Lancashire over the next ten months.
New wires are being installed and steelwork repaired and renewed on the 345 pylons which make up the 116km long electricity transmission line which runs between Carlisle and Quernmore.
Workers are currently carrying out repairs and upgrades in the Halton and Caton area.
The line is part of the network of overhead lines, underground cables and substations that carry high voltage electricity across the country.
The work is being carried out between March and December and there will be no interruption to electricity supplies during the work.
National Grid is writing to homes and liaising with landowners directly affected by its work on the lines in the area.
Advance notice will be given of any road and footpath closures. A special contact number has been set up for people to ring if they have questions about the work. The number is freephone 0800 389 7235.
