According to Tennessee Dept of Transportation.

Alcoa Highway impacts from Woodson Drive to UT Hospital/Cherokee Trail interchange, Monday, Oct. 13, 2025 to Friday, Oct. 17, 2025.

* rolling roadblocks will take place in short intervals (approximately 20 minutes each) and will be spaced out to allow traffic to return to normal flow between operations. These rolling roadblocks will be intermittent each day between 9 a.m. and 3 p.m.

* flagging operations on the ramp from northbound Alcoa Highway (US 129/State Route 115) at the traffic signal at Cherokee Trail and along Cherokee Trail, intermittent each day between 9 a.m. and 3 p.m.

* beginning on Wednesday, October 15, and continuing through Friday, October 17, the right northbound lane of Alcoa Highway (US 129/State Route 115) will be closed between Woodson Drive and Cherokee Trail each night between 7 p.m. and 6 a.m

Note, these rolling roadblocks and lane closures can affect traffic past John Sevier Hwy. And further into Blount County.

Beginning today, Dec. 2, 2020, "access from both Barber Hill Road and Montlake Court to Alcoa Highway will be closed permanently."

TDOT has descriptions of how to get on Alcoa Highway using alternate routes, listed under Construction Updates, December 1, 2020. There is also a video.

For example,
"Montlake Drive traffic to Alcoa Highway northbound: Will travel east around the round-a-bout at Montlake Court, cross the bridge, turn left onto Collector 3, turn left onto Woodson
Drive and then turn right onto Alcoa Highway northbound.

Montlake Drive traffic to Alcoa Highway southbound: Will travel south at the round-a-bout at Montlake Court, follow along Collector 6 (at the base of the large wall) and the turn right
onto Alcoa Highway southbound at the stop sign. "

This is assuming the driver will be able to identify Montlake Court, Collector 3, Collector 6, etc.

Getting on Alcoa Highway northbound at Woodson Drive is no fun. I think I'd go on down to Maloney Road, go over the bridge then get on Alcoa Highway northbound. Either way, since the last time I drove in that area it is obvious they need better merge lanes.

Beginning Sunday, Dec. 3, 2017, motorists will no longer be able to turn left off of southbound Alcoa Highway to Woodson Drive. Motorists going northbound will still be able to exit right onto Woodson Drive.

The detour will be in place through March 2018, depending on the weather.

I saw the sign warning of the pending turn lane closure. I wondered how they were going to detour the traffic to Woodson Drive. Now I know.

The detour will take motorists to John Sevier Highway, three miles down Alcoa Hwy, where there is not a great interchange. It appears this detour is the best alternative. However, for those that know the area there are other options. One would be to go Chapman Hwy. to Maryville Pike. For the adventuresome, you could go Cherokee Trail to Edington Road, then Maryville Pike. There are a couple of other roads where motorists could cut through some neighborhoods, but you would have to be wary of going left on Alcoa Hwy. and know the backroads.

What: Attend TDOT meeting in Alcoa to Stop Alcoa Hwy Relocation Project
When: Thursday, May 18, 2017 - 5:00pm
Where: Alcoa Public Works building. 725 Universal Street, Alcoa, TN

TDOT has announced a public meeting to gather public input on the plans for an Alcoa Highway Bypass, a 6-8 lane road proposed through Alcoa and Rockford.

The City of Alcoa originated in 1918 as the first planned community in the State of Tennessee. A planned community is any community that was carefully planned from its inception. In the original plans, Alcoa, Inc., included one acre of park space for every 100 city inhabitants. In addition, between 1918 and 1924 approximately 300 shade trees were planted along city streets and parks. This type of planning has gone by the wayside.

Please help us out. We do not need a colossal roadway through our communities. The proposed Alcoa Highway bypass will come too close to the treasured Springbrook neighborhood and community park. It will take away the Pine Lakes Golf Course. It will also negatively affect the Northwood, Glenmore Estates, and Cedar Hill neighborhoods as well as five other impacted areas. Very little noise abatement is planned. All of the existing Alcoa Hwy in Knox County and the majority in Blount County is being widened. Why can't the just widen the existing highway in the Alcoa area?

The meeting will be held:
Thursday, May, 18 2017
5 - 7 PM

The meeting location will be held at the Alcoa Public Works building.
725 Universal Street
(off of N. Wright Road/E. Edison Street, just north of Springbrook Road and east of Springbrook Park )
Alcoa, TN 37701
865-380-4800

TDOT will take written comments, a court reporter will be available for verbal comments, and you can speak with TDOT representatives.
Reference the Blount County SR-115 (US-129) projects (Alcoa Hwy Bypass) in your comments.

Please attend to express your opinion for NO Alcoa Highway Bypass.
