Highway sound barriers as border fences? (Construction would be economically, physically feasible, say experts)

As discussion of erecting a security fence along U.S. borders with Mexico and Canada heats up, some analysts say it's possible Washington could economically erect thousands of miles of barrier to keep out illegal aliens, smugglers and terrorists, for about half of what the Pentagon is spending a month to fight the war on terror.

The idea, they say, is to erect a structure similar to barrier walls built along highways to reduce sound. They are sturdy, tall, not easily scaled and, most attractively, affordable.
