Interchange Four and a Half
But now this raises the issue of the names of these interchanges. In the olden days it was very simple - you had Trade Centre (i/c 1), Defence (i/c 2), Safa Park (i/c 3), Police College (i/c 4), Middle-of-Nowhere (i/c 5), Jebel Ali Village (i/c 6) and Jebel Ali Port and Free Zone. Now we have the new interchange (and it's a beauty - long, soaring, gorgeous bridges) between 4 & 5. Shortly we will have a smaller one between 4.5 and 5, so that will be four-and-three-quarters. There's also the Binned Potato Interchange between 5 and 6, and a one-way bridge into Al Quoz between 3 and 4. The old interchange five is now a no-go zone while it is re-built over the next couple of years.
The old interchanges used to have big signs on them that told you what they were called. The new ones have massive adverts for Emaar, Mall of the Emirates and Ibn Battuta. Very confusing for newcomers, I'm sure.
