How about we kick out all the illegals, and close the border so traffic is reduced by the number of coyotes, black marketers and drug runners we shut out. Just kicking out Texas Illegals should eliminate the need for more roads in and of itself. Without the Illegals the roads we have now would handle the traffic with no stress.
Without illegals here in Houston, traffic would decrease signifigantly, and at least 50% of all accidents would never occur.
