Tuesday morning in Downtown Knoxville, crews will begin working on upgrades to the 500 block of North Gay Street, and that could cause some traffic problems.
The road runs under the I-40 overpass to West Fifth Avenue.
Crews will be putting in more landscaping, better street signs, and more lighting.
The city council approved the changes back in June. They also voted to improve storm water issues in the area.
At times, crews will have to shut down traffic to one lane typically between 7 a.m. and 5 p.m.
Construction is expected to last until the end of the year.
