Council chiefs have unveiled a “contraflow” cycle lane in Preston.
The new lane in Marsh Lane runs in the opposite direction to the one-way traffic flow.
Alistair Simpson, senior cycling officer for Lancashire County Council, said: “National guidance on the design of cycle facilities favours the use of cycle lanes on one-way streets to allow cyclists to travel in both directions. They help cyclists get to where they want to go via more direct routes, and provide an alternative to busy main roads. In this case the new cycle lane offers better access to the university.
“This new ‘contraflow’ cycle lane has long been an aspiration of local cycle groups.”
But keen cyclist Simon Halliwell said the layout was an accident waiting to happen.
Simon, of Lea, said: “I cycle to work every day and use Marsh Lane, and this will surely cause many accidents.”
