O'FALLON, MO. • Work crews will open the new westbound Interstate 70 exit to Highway K and East Terra Lane, 70's north outer road, on Friday sometime before the afternoon rush-hour period.

The Missouri Department of Transportation said the new ramp from East Terra to westbound 70 also will open. Meanwhile, the current westbound 70 exit to K will close.

The changes are part of an overhaul of I-70 interchanges and outer roads in O'Fallon aimed at improving traffic flow.
