Greenery under Bridges & Overpasses

How the city of  Chengdu in China has used vertical gardening on the columns of overpasses is an example for all of us.

Pakistan all urban cities should follow this because in the last two decade hundreds of bridges and overpasses have been constructed here. So are the rise in numbers of vehicles in the country, releasing huge amount of carbon emissions

If these bridges and overpasses are decorated with greenery as done in Chengdu via putting on a dreamy filter with their piers covered by greening ivy leaves, it will greatly help to •Arrest Carbon emissions •Keep the Environment •Improve Air Quality
