The road is part of the historic Hertford Road, a route running north from Bishopsgate along the western side of the Lea Valley, through Stoke Newington, Tottenham, Edmonton, Waltham Cross, Cheshunt and Broxbourne to Hoddesdon, where it branches split to Hertford and Ware. Although the southern end of the Hertford Road between London and Tottenham is thought to follow the Roman Ermine Street, the modern road takes a more easterly course through Edmonton and Enfield.
The route is featured in William Cowper's 1782 comic ballad The Diverting History of John Gilpin, which describes the chaotic progress of the hero along the road from London to Ware and back, failing twice to stop his borrowed horse at his intended destination, the Bell in Edmonton.
The route from London to Ware was designated in the early 20th century as the southern section of the A10. Large sections were progressively by-passed by dual carriageway. The A1010 was the earliest section to be by-passed, by the Great Cambridge Road (originally designated A108) which runs parallel about 1 mile (1.6 km) to the west. Unlike the new road, which developed as an important centre of the electronics industry, the old road remained generally more commercial and residential in nature.
The southern end of the A1010 is named Tottenham High Road, becoming Fore Street from Upper Edmonton to Edmonton Green. For the northern part the name Hertford Road is used, passing through Ponders End, Enfield Highway, Enfield Wash, Freezywater and Bullsmoor. At Waltham Cross the old route is the pedestrianised High Street, which the designated A1010 by-passes, terminating at the A121. To the north the historic route to Ware is now designated as the B176 and A1170.
