State Route 198 (SR 198) is a relatively short, secondary north–south state highway located in West Tennessee.

Although this road runs in a generally east to west direction, The Tennessee Department of Transportation [2] has designated this as a north to south highway.

It passes through Beech Bluff at approximately 3.2 miles (5.1 km) north of its southern end.

For most of its entire length it is known as the Beech Bluff Road until it nears the city limits of Jackson.

It is then designated as East Chester Street until its termination.
