Bogotá is turning the stretch of Calle 26 west of Ave. Decima into the city's newest street art gallery. The avenue was widened recently to add a TransMilenio express bus lane to the airport - altho that's still waiting to be completed. During the work, they demolished building, leaving big vacant wall spaces.
Strangely, the city also left vacant lots and installed benches where nobody ever sits. But those are other stories.
Bogotá's City Council recently declared street art to be 'public patrimony' and made it legal where the property owner gives permission.
