The Enbridge Gas London Lines Replacement Project is a vital construction project serving various communities in Middlesex and Lambton Counties.

The project requires the installation of approximately 82 kilometres of 4-inch and 6-inch diameter natural gas pipeline. The project is designed to improve system integrity and provide operational flexibility by replacing the two current pipelines in the area (known as the London Lines).

The London Lines Replacement Project will also include the construction of 8.4 km of a secondary 6-inch pipeline which will reinforce the new pipeline from a source near Strathroy. This will start within the Township of Dawn-Euphemia near Dawn Valley Road and Bentpath Lane. It will then continue through the municipality of Southwest Middlesex and will end at two locations: within the Municipality of Middlesex Centre at a newly rebuilt station on Komoka Road, south of Glendon Drive; and at a newly rebuilt station at Calvert Drive and Sutherland Road in the Municipality of Strathroy-Caradoc
