State Route 13 Improvements

Overview

The aproximately 4-mile project for State Route 13, begins at the Humphreys/Perry County line, south of Old State Highway 13 (Tennessee Gas Drive), and ends near Loretta Lynn’s Kitchen, north of the I-40 Interchange . It includes the widening of SR 13 from two to four lanes with a center turn lane as well as the widening and replacement of the bridge over Interstate 40.

Purpose and Need

SR 13 connects multiple communities to I-40 including, Waverly to the north and Lobeville to the south. It was identified in the IMPROVE Act. The project will improve access to I-40 from State Route 13 to increase capacity and support development in the County. It will also address safety issues, design deficiencies and replace and widen the bridge over I-40. 

Design

The existing typical sections shown are broken into 2 sections, north of I-40 and south of I-40. The existing road south of I-40 consists of one 11 foot lane in each direction with 4 foot shoulders. The existing road north of I-40 consists of one 11 foot lane in each direction and one 11 foot dual left turn lane with 4 foot shoulders.

The proposed typical sections shown below are broken into 3 sections, a rural section (no curb and gutter) south of I-40, an urban section (with curb and gutter) from approximately a quarter of a mile south of I-40 and an urban section (with curb and gutter) north of I-40.

The rural section consists of two 12 foot lanes in each direction with a 12 foot dual left turn lane and 12 foot shoulders (10 feet paved), the urban section south of I-40 will have two 12 foot lanes in each direction with a 12 foot dual left turn lane with no shoulders adjacent to the curb and gutter, this section will transition just south of the new I-40 bridge to a three lane section with one 12' lane in each direction and a 12 foot dual left turn lane with 6 foot shoulders with curb and gutter, this section will extend across the new I-40 bridge and continue to the end of the project.
