In fact, many , many, many years ago, I enjoyed a documental in the spanish television when this concret barrier was developed, and I remeber very well that it was filmed in New Jersey. Thye made many car test against the barriers and was a incredible invent.
But I not expected is that it was called Jersey barrier, which I discover few time ago.
Surely there are now many variations and types made in all countries, but the original is the original!
Thnaks for the review too.
