Higham Hill Lib Dem ward councillors Peter Woollcott, Patrick Smith and Sean Meiszner, have been campaigning for a new route between Highams Park station and Tottenham Hale for years.
They argue that as the area is one of the most deprived in the country, and more than a mile from Walthamstow Central Station, a route is desperately needed.
The group met with Lib Dem London Assembly Member Caroline Pidgeon on Thursday who will lobby the mayor and Transport for London (TfL).
Mr Woollcott said the route would bring much benefit to the area.
He said: “There are proposals to build 240 homes in Sutherland Road, 600 in Banbury Park, and the possible Walthamstow Stadium development, so we need facilities in place now.
"The existing 158 bus service from Stratford to Chingford Mount is extremely unreliable and does not really serve the people of Higham Hill that well.”
The new bus route being proposed would run for six-and-a-half miles from Tottenham, along Ferry Lane, Billet Road, Hale End Road, before finishing at Highams Park Station.
“The Highams Park area really does need a direct bus link to the major rail and Tube interchange at Tottenham Hale.
“Several secondary and primary schools would benefit from the new route, which has been developing for six years and we now need some action.”
