Some of this is absolutely superb work
The major highway that cuts East-West through Guadalajara also has some major artwork underneath it’s bridges. A couple of years ago, the government sponsored a graffiti murals before the start of the Pan-American games hosted by GDL. They decided some nice murals would look better than the dinginess of an overpass. Today, this is a great place to look at murals, but have your wits about you, lots of drug deals happen here and that brings shadiness.
