A Stack of Freeways...

On a visit to LA a few years ago I was impressed with the freeways and the engineering marvels that were the freeway interchanges. I recall one that was stacked 9 levels high.

Our own freeways are pretty ordinary by comparison. The spider-web of roads over Darling Harbour is about the best we have. But, the new interchange at Walgrove Road, at the intersection of the M4 and the new M7, is a marvel.

Very soon this mess will be the most impressive interchange in the country and I believe, the only one where you can exit one freeway and immediately enter another one.



Some smart guys working on this.
