Roadwork continues around Chattanooga during October 20–21, including traffic shifts at I-75 and Hamilton Place, daytime utility work on Signal Mountain Road and St. Elmo Avenue, and other resurfacing projects.
Overnight resurfacing affects I-24 in Marion County, while a long-term slope project keeps part of State Route 108 to a single lane controlled by temporary signals.
Drivers should follow posted restrictions and check current traffic information before traveling, as work schedules can change.
