State Route 28 (US 127) Grimsley Improvements - (Fentress County)

Project Alternatives

Preliminary Alternatives and Corridors Considered

During the initial stages of the Environmental Assessment, a preliminary range of potential alternatives and corridors was identified to help address the transportation needs in the study area.  These alternatives and corridors were developed as a result of public input. The preliminary range of options included:

  • No-Build Alternative
  • Corridor A- Utilizes the existing SR 28/ US 127 North alignment;
  • Corridor B-  Constructed on new location; and
  • Corridor C-Constructed on new location.

Refinement of Preliminary Alternatives and Corridors

Following the June 2008 public meeting, the range of alternatives and potential corridors was refined based on the results of preliminary environmental screening, consultation with resource agencies, and application of performance criteria.  During this process, TDOT conducted a field review with resources agencies to examine the potential alternatives and corridors.

The criteria used to evaluate how well potential alternatives/corridors would accomplish the purpose and need of the project were:

  • Ability to achieve the purpose and need for the project
  • In order for an alternative to meet the objective of system linkage, the alternative chosen must improve the roadway connection from Interstate 40 to the county seat of Jamestown. 
  • The alternative must effectively improve the flow of traffic using SR 28/US 127.
  • In order for the alternative to meet the objective of improved safety, the route should reduce the number of conflicts between vehicles on SR 28/US 127.
  • To promote economic development the alternative must create an easily accessibly and navigable route for new and existing businesses and industry by providing access to the interstate system.
  • Impacts to the environment, impacts to archeological and historical sites and parklands;
  • Involvement with hazardous material sites;
  • Socio-economic impacts; and
  • Support from the public and local officials.

The refinement process also included on-site reviews and reviews of existing data sources including Geographic Information Systems information (GIS) from local, state and federal agencies. Information collected includes city boundaries, land uses, community facilities, historic resources, wetlands, floodplains, streams, and soils. During this process, in September 2008, TDOT conducted a field review with resources agencies to examine the potential alternatives and corridors.

The following alternatives/corridors were evaluated during the refinement process:

  • No-Build Alternative- The No-Build Alternative would not improve SR 28/ US 127 between SR 62 in Clarkrange to approximately three miles north of Grimsley, Tennessee.

  • Corridor A- Corridor A utilizes the existing SR 28/US 127 North alignment. This corridor would involve widening existing SR 28/US 127 from a two-lane facility to a four-lane divided roadway or a four-lane roadway with a center-turn lane. Presently, SR 28/US 127 consists of two, eleven foot lanes with three to eight foot wide shoulders. The total length of the Corridor A is approximately 9.3 miles.

There are two proposed typical sections for this alternative:

  • In the vicinity of SR 62 to Banner Roslin Road, the proposed typical section would have four 12-foot travel lanes, a 12-foot continuous center turn lane, 10-foot shoulders, 2-foot gutters and 10-foot utility strips within approximately 104 feet of right-of-way. The shoulders would be adequate for use by pedestrians and bicyclists.

  • The second typical section would begin at Banner Roslin Road and end at the northern terminus of the project at Wright Frogge Farm Road. It would consist of a four-lane divided highway with 12-foot lanes, 12-foot shoulders, and approximately 52 feet of median within approximately 300 feet of right-of-way. The shoulders would be adequate for use by pedestrians and bicyclists.

  • Corridor B- Corridor B would be constructed on a new location. The proposed typical section would be a four-lane divided highway with 12 shoulders and a 52 median.

    Corridor B would transition from existing SR 28/ US 127 near the intersection of SR 85 (Kiley Road) and would tie back into the existing route near the terminus of the project. Presently, SR 28/US 127 consists of two, eleven foot lanes with three to eight foot wide shoulders. This corridor parallels existing SR 28/ US 127 along the western side.

  • Corridor C- Corridor C would be constructed on a new location. The proposed typical section would be a four-lane divided highway with 12’ shoulders and a 52’ median.

    Corridor C would transition from existing SR 28/ US 127 near the intersection of SR 85 (Kiley Road) and would tie back into the existing route near the terminus of the project.

    Presently, SR 28/ US 127 consists of two, eleven foot lanes with three to eight foot wide shoulders. This corridor parallels existing SR 28/ US 127 along the eastern side.

Alternatives to be Evaluated in the Environmental Assessment

Based on the results of the screening analysis, public input, and resource agency comments and concurrence, TDOT determined that the following alternatives should be dismissed from further consideration because they fail to substantially address the transportation needs and purpose of the project:

  • Corridor B
  • Corridor C

The following alternatives will be carried forward, refined and evaluated in detail in the Environmental Assessment:

  • No-Build
  • Corridor A (Build Alternative/Alternative A)

Detailed technical studies have been conducted on the alternatives carried forward in the Environmental Assessment in accordance with TDOT's Environmental Procedures Manual.

Alternatives to be Evaluated in the Final Environmental Document
Following the March 2011 Public Hearing, TDOT decided to revise the proposed design of the SR 28/US 127 Project to allow for the addition of a third typical section.  The proposed design also expands the right-of-way limits in some areas of the project from 104 feet to 300 feet.  These changes were necessary to accommodate a higher design speed as well as allow for higher levels of safety.
The No-Build Alternative:

  • This alternative would leave this portion of SR 28/US 127 as it currently exists, other than the continuation of routine maintenance as needed.
  • Serves as a baseline that other alternatives are compared against the other project alternatives.

Build Alternative (Alternative A)- Utilizes existing SR 28/US 127 North Alignment

The Build Alternative (Alternative A) utilizes the existing SR 28/US 127 North alignment.  This alternative would involve widening existing SR 28/US 127 from a two-lane facility to a four-lane divided roadway or a four-lane roadway with a center-turn lane.  Presently, SR 28/US 127 consists of two, eleven foot lanes with three to eight foot wide shoulders. The total length of the Build Alternative (Alternative A) is approximately 9.3 miles.

There are three proposed typical sections included within the limits of the Build Alternative:

  • From SR-62 (project start) to Little Road the typical section consists of five lanes including two travel lanes per direction and a two-way left-turn lane.  This would be an urban section with curb and gutter in 104 feet of right-of-way.      
  • From Little Road north to South York Court the five lane section continues but transitions to a rural section with shoulders.  The right-of-way limits also increase to 150 feet.
  • From South York Court to Wright Frogge Farm Road (project terminus) the typical section becomes four lanes (two travel lanes per direction) with a 52-foot divided median.  The right-of-way limits are 300 feet.
