Construction on Interstate 70

Construction on Interstate 70 begins Monday in Columbia. The $2.8 billion project is expected to be finished by 2030.

Construction crews began work Monday night on an ambitious $2.8 billion project that will expand Interstate 70 to three lanes across Missouri.

Crews are first tackling a stretch from Route J at Millersburg to Route M at Hatton, 7 miles of a 20-mile section that will ultimately add a third lane in each direction from Columbia to Kingdom City.
