From SR-29 in Dayton to West of TN River
Because the project is in the Environmental Phase, and has not yet progressed to the Design Phase, there are no design documents for the project. Currently, seven project alternatives are being considered. They are discussed in more detail below.
A No-Build option and 1,000-foot wide study corridors were developed during the TPR process. Four of the corridors were on new location and the fifth followed the existing SR-30 route (see map). Following the two public meetings, a sixth study corridor was added to the project as a result of public input and support. Much narrower roadway alignments will be developed within the study corridors, based on the findings of technical studies and public, local government and agency input. The following describes the corridor options:
Option 1 – Whites Flat Road: Option 1 begins at SR-29 about six miles north of the current intersection of SR-29 and SR-30. It follows Whites Flat Road from SR-29 eastward, connecting to existing SR-30 near SR-302 in Old Washington. It then follows existing SR-30 to the eastern project terminus, west of the Tennessee River Bridge.
Option 2 – New Location: Option 2 is primarily on new location. It begins on SR-29 approximately two miles north of the existing intersection of SR-30 and SR-29. From SR-29, it follows Walnut Grove Road’s existing alignment for approximately two miles. It then departs from Walnut Grove Road (west of White Hollow Road) and proceeds northeast on new alignment until it connects to existing SR-30 west of Whites Flat Road. Option 2 follows existing SR-30 east to the eastern project terminus, west of the Tennessee River Bridge.
Option 3 – Walnut Grove Road: Option 3 uses the west portion of Option 2 (following Walnut Grove Road), then deviates from Option 2 and provides a connection to Option 5 west of White Hollow Road. It connects to SR-30 and then follows the existing SR-30 corridor east to its eastern terminus, west of the Tennessee River Bridge.
Option 4 – Walnut Grove Road: Option 4 uses the west portion of Option 2 (following Walnut Grove Road), then deviates from Option 2 and provides a connection to Option 5 west of White Hollow Road (farther west than Option 3). It connects to SR-30 and then follows existing SR-30 east to its eastern terminus, west of the Tennessee River Bridge.
Option 5 – Improvements to Existing: Option 5 follows existing SR-30 for the length of the project, from SR-29 to west of the Tennessee River.
Option 6 – White Oak Road: Option 6 follows White Oak Road from SR-29 to the intersection of New Union Road and SR-30, follows existing SR-30 to the end of the project at the Tennessee River Bridge approach.
A No-Build Option will also be considered during the NEPA process. This involves making no improvements to existing SR-30 beyond routine maintenance and repairs. This option also serves as a baseline for all other options considered.
