Mobil On the Run is back in business at the intersection of Highway K and Highway N in O'Fallon.

The Country Club Car Wash, located at 2999 Highway K at the northwest intersection, across from the Mobil on the Run's old site—added the gas station's convenience shop to its location.

Mobil on the Run stations and Country Club Car Wash locations are under the same ownership, so the only change is the type of convenience store on the inside.

Construction began on both projects in early May 2012. While Mobil On the Run was completed this week, CVS Pharmacy is expected to open its doors in O’Fallon by late October.
