Claiming truly free roads

The Texas Toll Party in San Antonio is opposed to the building of toll roads in the Alamo City. They're entitled to their view, but I don't think it helps their argument to claim that an absence of toll roads means that a highway could possibly be built for free. Witness the following quote from this post:

If they get rid of just these toll equipment [sic] not to mention the toll lanes (that only half of all motorists can use) and just build what's needed, the road is 40-100% less money to build and EVERYONE can drive on it. [emphasis added, except for the all-capped word]

Everyone can drive on it. And it could cost nothing to build. As long as there is no toll equipment. Or toll lanes. Got it?
