, the road takes two courses through the town - the first is a concurrency with the A1 round the new town to the junction at Langley Sidings. The second is a route through the town itself, following closely the route of the old Great North Road. The two routes converge and form a northern bypass for the suburb of Broadwater (the old Hertford Road through Broadwater has been closed to motor vehicles since the 1990s, to prevent rat-running).

The next 3 km of road is the only remaining original piece of the route, travelling through the villages of Bragbury End

 bypass, the road was completely re-routed along the course of the B1001 from Watton-at-Stone to meet the modern A10 at Ware. The B1001 itself remains for a short distance, linking the modern A10 with the old road in the town centre (now known as the A1170).

A602 Corridor Improvements

Due to the old nature of the road it suffers from congestion, substandard structure and a high level of accidents. As such a series of developments along much of its stretch where proposed in the 2006-2011 Local Transport Plan. These comprise a number of different schemes but are put forward together under the collective title of ‘A602 Corridor Improvements’. The various schemes involve work on junctions, road re-alignment to make severe bends safer, structural maintenance and road safety schemes. It also considers the construction of a bypass at Hooks Cross but this remains in the early proposal stage. In 2006 the estimate cost of the whole strategy was given as between £14.3 and £15.8 million. Each individual scheme is intended to be bought forward as and when funding becomes available.. The section between Sacombe Pound and Watton-at-Stone gained planning permission for work to commence in summer 2007 though work was never started, so all sections remain at the proposal stage.
