SR 97 proceeds northeast out of town, passes through Cushing, and then enters Warren, where it ends at US 1 near the Oyster River, just west of Thomaston.

The Maine State Prison is located on SR 97 in Warren, near the Cushing town line.

When it was first established in 1929, SR 220 existed as a strange V-shaped route in its southernmost stretch from Waldoboro to Warren (via Friendship).

However, there is no indication of this in the field, as no signage for SR 97 exists on Harbor Road.

In addition, its defined length, 9.5 miles (15.3 km), is equal to the distance between SR 220 and US 1 in Warren and is confirmed by the route's signage.
