State Route 162 (Pellissippi Parkway) Extension

Blount County

At the request of the Blount County Commission and in conjunction with the Virtual Design Meeting held in April 2021, the Tennessee Department of Transportation (TDOT) will host an in-person Design public meeting on September 21, 2021, to gather additional public input on the proposed project in Blount County on SR-162 EXT (Pellissippi Parkway), from SR-33 to SR-73 (US-321).  The proposed State Route 162 Pellissippi Parkway Extension includes construction of a new transportation corridor, extending Pellissippi Parkway from its current location at SR 33 (Old Knoxville Highway) to SR 73 (US 321/Lamar Alexander Highway) in Blount County. The length of the proposed extension would be approximately 4.4 miles. The purpose of this Design public meeting is to allow property owners and the general public an opportunity to comment on the proposed design elements. A formal presentation followed by a short Q&A will begin at approximately 5:30 pm EST. Beyond this initial presentation and group Q&A, most of the evening will be reserved for one-on-one conversations between TDOT representatives and individual attendees. TDOT asks that questions and comments raised during the group Q&A be limited to the general design of the project and that
questions or comments regarding a single property be reserved for the one-on-one conversations while reviewing project displays.  The meeting will be held from 5:00 p.m. until 7:00 p.m. EST at Heritage High School, 3741 E Lamar Alexander Parkway, Maryville, TN 37804.


The proposed project consists of developing a new controlled-access four-lane
highway with a concrete median barrier wall, and grade separated interchanges.

Purpose and Need

Currently, the roadway has several deficiencies. The transportation needs can be summarized as follows.

  • Limited mobility options in Blount County and Maryville due to the primarily radial roadway network that now exists
  • Poor local road network with substandard cross sections.
  • Lack of northwest/east connection of Alcoa and Maryville to help serve:
    • Expanding residential development occurring in eastern Alcoa and the Knoxville area to the north
    • Increasing demand for trips between Maryville and Alcoa, and the Knoxville area to the north
  • Safety issues on roadways in the area, including roads in the Maryville core that through-travelers between northern and western portions of the county and the eastern portions of the county must pass and numerous rear-end crashes and angle crashes have been reported due to high volumes of traffic and lack of access management along the roadways
  • Traffic congestion and poor levels of service on the major arterial roads in the study area (US 129, SR 33, US 411 and US 321)

The purpose of the project is to improve safety and mobility. The primary benefits include:

  • Enhance regional transportation system linkages.
  • Improve circumferential mobility by providing travel options to the existing radial roadway network in Blount County, Maryville, and Alcoa.
  • Improve roadway safety on the existing roadway network, including the Maryville core.
  • Achieve acceptable traffic flows (level of service) on the transportation network or not adversely affect traffic flows on the existing network.

Additionally, the parkway extension is designed to support community and growth management goals and minimize adverse impacts to neighborhoods and businesses, farmlands, and the natural and cultural environment.

The proposed project would be constructed in part with federal funding and is, therefore, subject to the requirements of the National Environmental Policy Act (NEPA). An Environmental Impact Statement (EIS) has been prepared to meet NEPA requirements. The Record of Decision (ROD) for the proposed project was signed by FHWA on August 31, 2017, and is available in the Library section of this project.
