The economics of Texas roads

I grew up in northern New Jersey, where you must do a convoluted U-turn (think Rt. 17) to visit the other side of the highway.  I live in Northern Virginia, where you simply turn left into the strip mall of your choice, but you face an intimidating array of traffic lights along the way.

A location theorist might worry this encourages too many shops to line up in a straight row along the main road, rather than clustering in a more circular fashion.  Who cares, I say?

Can you think of economic arguments against this arrangement?  Comments are open…

I might add that the elevated Rt.10 in El Paso is aesthetically impressive as well.  Headed west, to your right is the city and mountains, ahead of you is New Mexico, to your left is Mexico Mexico, all in one fantastic blick…
