The A602 is a road linking Hitchin in Hertfordshire, England, with A10 at Ware in Hertfordshire, via Stevenage. The course of the road has changed significantly since the 1960s with the construction of several bypasses and relief roads. In Hitchin, the road starts at a junction with the A505, and follows a relief road round the south of the town centre, before re-joining the course of the original route for 0.9 miles (1.4 km). The village of Little Wymondley is bypassed by a dual carriageway route to the A1 junction at Corey's Mill.
