Gregg says the $100 million that will be used for the project could be used in other places in the county.
"Another road in our county that needs attention, and you will get universal agreement on this, is Alcoa Highway," said Gregg, "Which is a death trap."
Gregg also says the project will not help with the flow of traffic through the county.
TDOT officials say they feel the project needs to be completed.
"TDOT has worked with local officials," said TDOT spokesperson Mark Nagi. "We've met with the folks with Citizens Against the Pellissippi Extension Project, as well. We feel that extending the Pellissippi Parkway is something that's not only good for folks in Alcoa and Maryville, and Blount County area, but this is a regional roadway going to and from the Smoky Mountains, going to and from East Tennessee."
TDOT officials say the project is still at its very early stages, and it will be years before construction would even start.
Members of CAPPE say they plan to continue to fight, and are planning fundraisers in the future to raise money for legal counsel to stop the project.
