Project Overview

Joint Venture of Sacyr, Wills Bros Ltd and Somague  have been awarded the contract and are responsible for the design and construction of the project roads.

This major flagship infrastructure project will provide 25.5km of new dual lane carriageway between Dungiven and Drumahoe, including a bypass of Dungiven, with roundabouts connecting the scheme to the existing road network at either end.

The A6 is a strategically important route as it connects the North West to Belfast and beyond. The existing road carries around 15,000 vehicles per day and with traffic levels continuing to grow, this very significant investment will greatly improve road safety and journey times by reducing congestion.
