Leftwich Bridge Access (also known as Sowell Mill Bridge) is a gravel access area on the Duck River in Maury County suitable for canoes, kayaks, and motorized boats.

The access point has limited parking and offers river access from both the left and right sides, though launching motorized boats can be difficult due to gravel, mud, and a drop-off to the river.

This location serves as a popular put-in or take-out for paddlers, with the 5. 5-mile stretch to Howard's Bridge taking 3-5 hours to paddle through the scenic Yanahli Wildlife Management Area.
