i spotted these barriers at the avenues as you enter to carrefour and wondered what took them so long! looking at people pushing their trolleys through the isles and between the fashion shops was not a good sight, but i guess from now on this will come to an end.
nevertheless, with the kind of traffic the avenues is attracting, people will still park away from carrefour and probably carry all their grocery bags back to their cars now that the trolleys are stuck behind bars! no a better sight i guess.
that's what happens when you build something so big without properly studying parking solutions - a multi-level parking would have been ideal for that matter.
