Apirchik,
The total cost cost being billed to my credit card in the US about 4 weeks after my Hertz rental this summer was $7.50 for using Hwy 6.

While true that Route 90 is not cut through Tel Aviv, I think it is a bit inaccurate to say it goes through Jericho. A simple look at a map will belie that. It runs along side it, yes, but not through it. (On a map you can see how the road actually curves way to the east to avoid it). There are a few tiny villages 90 cuts through, but the largest has a population of about 200 visible from the road.

So there you have it, 2 jews - 2 opinions- who'd guess.
