But the capital started to sprawl, first along the river from the City to Westminster, and then north past Soho (in medieval times, the king's hunting grounds) to Oxford Street and beyond.
The road would begin at a point close to the junction of the Harrow and Edgware Roads and head due east past the northern end of Marylebone Lane to Tottenham Court, and from there via Battle Bridge, St Pancras, to the top of St John's Street in Islington, a short distance from the market.
Construction at first was fairly crude, involving mainly cutting down hedges and filling in ditches, and the route was bounded by fence posts.
During the remainder of the 18th century the northern edge of London's built-up area moved towards the road, finally engulfing it, although the 50 feet (15 m) building margin was enforced.
By 1829 much of the road was bordered by fashionable houses, and in that year that the first horse omnibus service in London was established by George Shillibeer.
His example was followed by many others, and the route became the main artery for such traffic for the remainder of the century, linking the sought-after north-western suburbs of 'Tyburnia'[2] with the financial centre (the City of London).
