The B197 through Graveley becomes North Road as it approaches Stevenage. This is officially the busiest road in Stevenage at peak times. It is also a major approach to Lister Hospital serving the whole of North Herts, Stevenage and beyond.

The problem junctions are with A602, the entry into the Old Town. Improvements might ease the tailbacks but insufficiently to compensate for the extra traffic from NS1 namely traffic from hundreds of houses forced onto this road. Other or extra exit points would still problems.
