Drivers have been warned to expect delays while giant electricity transformers are delivered to a new substation.
National Grid will move the huge pieces of machinery to its final destination in a field off Essendine Road, between Ryhall and Essendine, tomorrow (Wednesday) and Friday.
The 97-tonne transformers arrived by sea from Germany earlier this month.
The transformers will be flanked by private escort and will travel at a maximum speed of 30mph. The vehicle carrying them is 35 metres in length, 3.8 metres wide and 4.6 metres high.
To ensure the delivery is made on time, some street signs at the junction of the A6121 and Essendine Road will be temporarily removed until the second transformer has been delivered.
The machinery is expected to arrive between 4pm and 5pm on each day. Roads will not be closed but the size of the load means that some will need to be kept clear of vehicles.
The route is from the A1 southbound onto the B1081 to Great Casterton, left onto Ryhall Road, right onto the B1176, left onto the A6121 and right onto Essendine Road.
