The project would form part of the strategic roads network, and deliver government aims for a more efficient, safer and sustainable transport network, supporting and encouraging long-term prosperity in the region.

Scheme development work will commence immediately, leading up to an anticipated Public Local Inquiry in winter 2016/7. Upon successful completion of the statutory processes, the second stage of the ECI work, construction, could start in spring 2018.

Andrew Wyllie, Chief Executive of Costain, commented:
