The proposed Morpeth northern bypass has been granted development consent by transport secretary, Patrick McLoughlin.
Carillion was awarded the job in 2013.
The scheme involves construction of a single carriageway 3.8km long from Whorral Bank on the A197, north east of Morpeth, west to the A1 trunk road.
A new at-grade roundabout is to be created at the intersection of the bypass with the existing A192 at Lane End. The project also includes a new standard grade separated junction with slip roads and a “dumbbel” roundabout arrangement, to provide ‘all movements’ access to the A1 trunk road and a link to St. Leonard’s Lane.
The planning application was submitted by Northumberland County Council for consideration in July 2013.
Construction is likely to start in the spring
