Missouri transportation officials are embarking on a plan to improve much of the state's 5,600 miles of major highways in the next five years. Efforts include the usual stripping, signs and paved shoulders. The state will also smooth out much of the pavement, a move that officials say will improve fuel economy by 2.4 percent. Considering Missourians log 103 million miles of travel every day, officials estimate up to $100 million in savings every year.
