[3] Public consultation regarding the roads was started in November 1997 about a decade before construction began and ended two months later in January 1998.
The original road plan had it running through Cawston and not around it but the extra funding was quickly found to change this.
25 acres (100,000 m2) of wildflowers would be planted[8] and several 'balancing pools' dug to try to help cancel out the negative environmental impact of the new road.
After months of building temporary service routes, major earthworking started in May 2008 along the southern section of the road.
[11] For the rest of the year the roundabout at the south end of the road, along with strengthening of existing bridges started.
In January 2009 industrial contaminants were found on a part of the proposed route on land formerly owned by Cemex, one of whose plants are next to the road.
