A campaign group in north London has decided to take legal action against Enfield Council's decision to go ahead with their cycle scheme.
The route from Palmers Green Library to Enfield Town, will have a 1.8 metre wide segregated lane on each side of the road.
Campaigners say the loss of residential and shop parking along much of the route, will lead to a drop in trade in the area.
They're concerned this could force businesses to relocate, or shut down completely.
Enfield Council said:
"The Council has just received notification that a judicial review has been issued. The Council does not consider it appropriate to comment as the matter is before the Court."
