Essex bus routes 500 and 501 were commercial bus routes in the county of Essex, United Kingdom. Only the 501 remains (as an Essex CC contract on Sundays). The remaining route operates between Harlow and Ongar via Epping and North Weald. The 500 operated between Harlow and Epping alongside the 501 which continued on to Brentwood. In February 2011, Arriva withdrew the commercial service of route 500 and 501 on Mondays to Saturdays. The Sunday service of route 501 is operated under contract to Essex CC between Harlow and Ongar, and this still remains.
