When will construction on Alcoa Highway be done? | Know Your Knox

Three things in life are guaranteed: death, taxes and construction on Alcoa Highway.

Ok, so maybe the last one won't actually go on indefinitely, but it can seem like the never-ending road project.

The Tennessee Department of Transportation is in the middle of the Alcoa Highway Corridor Project, which is intended to improve 13 miles of highway that stretches from Knox to Blount County.

TDOT spokesperson Mark Nagi told Knox News that major infrastructure projects take a lot of time and money to complete.

Nagi said Tennessee is a "pay as you go state" so projects don't move forward unless funding is secured.

The construction also wasn’t all done at once and was split into several phases due to the sheer size of the corridor, according to TDOT.

The Alcoa Highway corridor project will address capacity and safety needs for the Blount and Knox County corridor.

What improvements to Alcoa Highway have been made so far?

Construction on the highway began in 2016 when TDOT began to improve a stretch from Maloney Road to Woodson Drive. That part was completed in the summer of 2023.

Only one other stretch has been completed so far, according to TDOT. That was a section north of Hall Road to a proposed interchange at Tyson Boulevard. That began in 2019 and was wrapped up in the summer of 2022.

What improvements to Alcoa Highway are coming?

Several more projects are in the pipeline and in various stages of construction.

A section of the highway, from Hall Road to Cherokee Trail, will be widened in three phases, in 2024, 2025 and 2026.

Woodson Drive to Cherokee Trail will receive several improvements, including two new roundabouts, lighting upgrades and two bridges. That project was started in 2023 and is expected to be completed in the fall of 2027.

TDOT is relocating the highway from a proposed interchange at Tyson Boulevard to SR 115 at South Singleton Station. The Alcoa Highway will be shifted east, curving around the current intersection at Pellissippi Parkway. Construction is split into two phases, with the first being completed in the fall of 2027 and phase two starting in 2028.

Alcoa Highway is undergoing a massive relocation. The project was split into two phases due to cost, TDOT Spokesperson Mark Nagi said.

A project is planned to improve the highway from South Singleton Station, south of Little River, but Nagi said TDOT doesn't have funding for that in place, so it's not possible to estimate a completion date.

Will this make your commute longer?

Your commute time could be longer depending on when construction is going on and where.

In terms of Cherokee Trail to Woodson Drive, Nagi said there eventually will be lane closures for overnight work. Rolling roadblocks will be used intermittently on weekdays during nonpeak hours from 9 a.m. to 3 p.m. Blasting activities will require closures, he said, but only for about five to 10 minutes.

Nagi said Cherokee Trail to Woodson Drive provides the most traffic delays because of its proximity to the University of Tennessee at Knoxville campus and UT Medical Center.

Local streets and interchanges will be open to the greatest extent possible, and TDOT will provide updates on its social media pages. Traffic alerts on Alcoa Highway also will be posted on TDOT's website.

Why are these improvements needed?

As East Tennessee continues to grow, it needs to make sure its infrastructure can accommodate all the vehicles it will see traveling through the region. Nagi said these updates are needed for three primary reasons:

To increase the capacity and level of service

To correct geometric deficiencies, which means working on the road's width, slopes and more.

To reduce crashes and improve safety

Which big brands started in Knoxville?

Whether you're new to Knoxville or a native of the Scruffy City, you still might not be aware of all of the famous names that were born here - specifically well-known commercial products seen and used by people everywhere, every day.

Why is Downtown West called that when it isn't downtown?

In a puzzling twist, a street far from Knoxville's city center bears the name "Downtown West Boulevard." The name is the remnant of a concept that never came to fruition. As it turns out, Angela Dennis shares, this naming choice can be traced back to the 1970s and some ambitious urban planning.

What would it take to get rid of the divisive James White Parkway?

The James White Parkway - the road to nowhere, as many deem it - is a short stretch of highway that carves a prominent division between East Knoxville and the city's core. Angela Dennis examines whether removing the mile and a half of highway that dead-ends the Sevierville Pike exit would even be feasible - or if there could be a more creative solution to bridge the separation this past infrastructure project caused.

Why are the University of Tennessee Vols' colors orange and white?

Buildings, vehicles, clothes and even food around Knoxville all pay tribute to Big Orange every day of the year, it seems, and even more so on game days. But where did the color combination of bright orange and white for the University of Tennessee Volunteers come from? Liz Kellar follows traces the daisy chain of this UT tradition (that's a hint!) back to the beginning.
