MoDOT Director Kevin Keith told state lawmakers that rapidly increasing amounts of traffic on I-70 could turn the interstate into a “graveled parking lot” within 15 years if the highway is not widened and repaved to make it safer and ease congestion. Costs for the improvements range from $2 billion to $6 billion. The plans would allow the state to repave the highway that’s mostly two lanes in each direction, add more lanes, install new medians and perhaps build separate lanes for large trucks.
