AIM created and performed the draft-project cycle path connecting Barcelona and Esplugues de Llobregat continuing Avenida Diagonal (under Park Cervantes)
The idea is based on use of a tunnel (now disused) intended exclusively for motor vehicle and converting it for pedestrians and bicycles
This new connection would create a new route for both pedestrians and cyclists. This new path would be a real alternative to motorized vehicles. Today the bikes have no direct access practical and pedestrians have to give a long roundtrip and has narrow sidewalks.
April 26th was published in La Vanguardia, that Metropolitan Area of Barcelona Authoriy (AMB), is performing the project and it would be a reality later this year (2014).
