New I-70 Ramps to Open at Route K (O'Fallon)

Nov. 28, 2018: Later this week the new westbound I-70 exit to Route K in St. Charles County will open to traffic.  The new ramp will also allow drivers to access the north outer road (East Terra Lane). When the new ramp opens, sometime before afternoon rush on Friday, November 30, the current westbound I-70 exit to Route K will close.  At the same time the new ramp from East Terra to westbound I-70 will also open.  Drivers on TR Hughes will once again have access to westbound I-70 via the new ramp on East Terra.  The changes are part of the I-70 Traffic Flow Improvement project.  For more information on the project go to
