Last month on the corner of Navy Road and Church Street in Millington, the gas station at 4990 Navy Road completed it’s transformation from a BP Station to a Marathon location with the change in the large sign display. The new digital price display was part of the change. Motorist in Millington and across the nation have seen a change in gas prices since January. In the Memphis area a few weeks ago, gas could be purchased as low as $1.75 per gallon. Now the average price for regular gas in Tennessee is $2.226. Across America the average for regular gas is $2.458 as of March 6. A year ago at that time, the national average was $3.47.
