Both Muswell Hill and Highgate Hill had slopes of 1 in 10 or so, which was just acceptable for pedestrians, or on horseback, but it was a major problem for wagons. A much more gentle gradient was needed. From Shepherd's Hill today one looks along Archway Road towards London down a narrow gorge, with Archway Bridge sailing across the skyline. In 1800 however one saw a long, almost level view of fields, with Hornsey Road running across in the distance. Beyond, and out of sight, was a steep drop, even sharper than Highgate Hill itself.
