At an intersection with the western terminus of Lauderdale CR 32 (Huntsville Road), SR 133 curves to the north-northwest.

On the northwestern edge of the park, after SR 133 has curved to a due west direction, it has an intersection with both the southern terminus of Lauderdale CR 47 (Old Jackson Highway South) and the northern terminus of Darby Drive.

It then reaches its northern terminus, an intersection with SR 20 (Savannah Highway/General John Coffee Highway).

SR 133 was likely formed around 1927 with the completion of Wilson Dam on the Tennessee River and the opening of it to automobile traffic.

It followed Wilson Dam Road north through Muscle Shoals to the TVA Reservation.

Big changes occurred in the early 1970s with the construction of Cox Creek Parkway, a northern loop for the city of Florence.

As part of a long-term "Patton Island Corridor", SR 133 was shifted to this new six-lane bridge.

The move necessitated construction of an overpass on Wilson Dam Road on the TVA Reservation.

After crossing the new bridge into Florence, the route turned east on Veterans Drive to rejoin Cox Creek Parkway just north of Wilson Dam.

As part of the ongoing Patton Island Corridor development, changes will be made to SR 133.

In Lauderdale County, the final extension of the project, from Huntsville Road to Helton Drive, opened on October 16, 2008.
