The Kentucky Transportation Cabinet today replaced speed limit signs with a 70 MPH decal on rural sections of interstates and parkways. There are close to 500 signs that will be transitioned to the new speed limit. In KYTC District 6 crews began the switch this morning at 8:30 and will be out working until all of the signs are complete. In all there are 40 signs that will show the new interstate speed limit. Motorists should also be aware that there are currently two construction projects in which the speed limit will reduce in the workzone to 60 MPH. One of the projects is widening I-75 to three lanes in Grant County just south of Dry Ridge and will continue south toward the Scott County line. The other project is on I-71 near Sparta, Kentucky. The speed limit will also be posting 60 MPH throughout this 3.2 mile section of interstate.
