The state Transportation Department warns lawmakers in a senate committee that both interstates 70 and 44 are in dire need of renovation. Chief Engineer Kevin Keith says both interstates work today, as long as there are no problems. But he says construction work, weather, motorists with a flat tire or traffic accidents all cause major traffic problems. He says that’s because the 50-year-old interstate system is simply outdated. Keith says congestion is a real problem with motorists with about 30,000 vehicles traveling on each interstate every day and he says each interstate is expected to have about 36,000 motorists a day by 2012. He says, by then, the problem could become unmanageable.
