Barcelona city hall is planning on improving Meridiana avenue. This is one of the main traffic arteries of the city with four lanes each way. Every day it is used by approximately 90 thousand cars. The administration intends to make it more comfortable for pedestrians, cyclists and public transport, and is examining various projects to achieve this. Authors of some projects propose maintaining the same sidewalk width, but narrowing the lane size in order to create a 4.5 meter cycling path in the middle. Others suggest decreasing the number of lanes and “greening” the adjacent areas.
