Costain, Jacobs secure contract for Simister Island interchange improvement project


Construction and engineering firms Costain and Jacobs have been appointed as delivery integration partners by Highways England for £138m M60 junction 18 Simister Island interchange improvement project.

Under the contract, both the companies will be responsible for the design and management of construction of the Simister Island junction improvement that connects the M60, M62 and M66 motorways in Manchester.

The Simister Island interchange is being used by approximately 90,000 vehicles daily and claimed be to be one of the busiest junctions in the North West.

The work on the project involves construction of a new loop structure to provide a free-flow link between the M60 eastbound to the M60 southbound.

This allows users to continue along the M60 without leaving the motorway, navigate the roundabout and re-join the same motorway.

Work also includes construction of a new two-lane free-flow road link from the northbound to westbound of M60, replacing the existing single-lane. It will also include widening of the M66 southbound to four lanes through junction 18.

The project will create extra capacity at junction 18 and help to reduce congestion, journey times and provide more reliable journeys for users and provide faster average speeds.

Currently a public consultation on the scheme is now being planned this winter and a planning application for the project is expected to be submitted in 2022.

Once plans are approved, work on the project are expected to commence by spring 2025.

Costain programme director Malcolm Bell said: “This is a critical project supporting economic growth in the North of England; improving traffic flow that connects businesses and communities.

“Costain will deploy digital tools to improve productivity and effectiveness throughout the programme to enable the timely delivery of safer, greener and more efficient roads.”
