The 14-mile (23km) route will run from Bradford city centre to Seacroft, in East Leeds.
The City Connect project, which is expected to be completed by the end of the year, has been funded by an £18m cash award from the Department for Transport and £11m of local funding.
The scheme also includes resurfacing parts of the Leeds Liverpool canal.
Coordinators say they hope the cycle way will encourage more people to make short journeys by bike and improve access to employment, skills and education.
The project is jointly managed by West Yorkshire Combined Authority, Leeds City Council and Bradford Council.





Where are we going?
£11 million local funding for a bike ride.

So its stuff all the potholes which are damaging all our vehicles, its turn all the street lights out, its make all the old folks homeless.

And how in Gods name are they going to resurface the Canal?

Oh well as long as we are looking after the cyclists who can't ride on roads
