Improvements? This is a complete waste of tax dollars and other money. It is only a high priority for special interests and NOT for the Texas commuter. Some things just don't change in a state that simply doesn't care all that much about its citizens.
The proposed N. MoPac toll lanes also are NOT in the best interest of the Texas community. They will do little to ease traffic on that expressway. The toll road mentality has run amok and Texas voters are permitting it to happen.
MoPac needs to be widened and it needs better road materials for repairs. The money "found" and borrowed for the toll lanes should be going instead to bettering the original roadway.
