KNOXVILLE – Motorists traveling on Alcoa Highway (US 129/State Route 115) in Knox County should be aware of upcoming road construction activities that will have a temporary impact on traffic.

Beginning on Monday, September 22, and continuing through Saturday, September 27, the contractor will perform rolling roadblocks on Alcoa Highway (US 129/State Route 115) between Woodson Drive and Cherokee Trail. These 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. to allow crews to safely mobilize equipment and perform rock excavation and clearing activities.

In addition, beginning on Monday, September 22, and continuing through Saturday, September 27, crews will be conducting 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 between the Alcoa Highway interchange and Medical Center Way. These flagging operations will take place each day between 9 a.m. and 3 p.m. to allow crews to unload materials and for trucks to safely enter and exit the work areas.

Also, beginning on Sunday, September 21, and continuing through Thursday, September 25, 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. to allow crews to safely clear trees and debris from the rock bluff along the northbound lanes.

This schedule is contingent on favorable weather conditions.  Motorists are advised to expect delays and use extreme caution in this area as workers will be present.
