London Buses route 422 is a Transport for London contracted bus route in London, England. Running between Bexleyheath and North Greenwich, it is operated by London Central.
Route 422 commenced operating on 16 January 1988 when route 122 was withdrawn between Bexleyheath and Plumstead. Route 422 was initially run by Bexleybus between Bexleyheath and Woolwich, providing an overlap with route 122 between Woolwich and Plumstead.
The poor performance of Bexleybus resulted in the route passing to Boro'line towards the end of 1988.
On 17 February 1992, Boro'line was bought out by Kentish Bus which was purchased by British Bus in 1994, who in turn sold out to The Cowie Group in August 1996.
On 23 January 1999, the route passed to London Central operating from their Bexleyheath (BX) garage with Leyland Titans introduced.
To coincide with the opening of the Jubilee line, on 25 May 1999 route 422 was extended from Woolwich to North Greenwich.
In 2000, the route was converted to low floor using Plaxton President bodied Volvo B7TLs.
In 2001, the route was rerouted in North Greenwich between the Bus Station and Blackwall Lane via Edmond Halley Way, West Parkside, and John Harrison Way.
In 2004, the route was extended daily from Bexleyheath Shopping Centre to Bexleyheath Garage.
In 2006, the route was rerouted towards North Greenwich via new bus-only link Road after Westcombe Hill.
