About Knoxville Traffic Cameras

TrafficVision.Live provides free access to 850+ live traffic cameras throughout Knoxville. Our platform aggregates feeds from Tennessee's 511 system and Department of Transportation cameras, giving you comprehensive coverage of traffic conditions across the region. Knoxville's traffic challenges stem largely from its geography and the convergence of two major interstate highways; Knox County currently maintains the highest daily driver average in the state of Tennessee. According to TDOT traffic monitoring data, the segment of I-40 near Hollywood Road alone processes nearly 205,000 vehicles per day.

The I-40/I-75 concurrency — running roughly 17 miles from the split at the I-40/I-75 junction near West Hills to the merge point near Watt Road — is the defining feature of Knoxville's highway network. This stretch processes over 218,000 vehicles per day, making it one of the busiest non-urban interstates in the Southeast. While the city maintains a relatively efficient average commute time of approximately 20 minutes, peak-hour congestion remains a significant factor, particularly during the evening rush between 4:00 PM and 6:00 PM.

Key Routes and Interchanges

I-640 provides a critical northern bypass around downtown Knoxville, connecting the east and west segments of I-40 without routing through the congested downtown core. This 17-mile loop handles significant traffic volumes, particularly during peak hours when commuters from north Knoxville communities like Halls, Powell, and Fountain City head toward employers in the downtown business district, the University of Tennessee campus, and the Oak Ridge corridor to the west. The I-640/I-75 interchange on the northeast side of the loop is a high-volume junction where Florida-bound traffic meets local commuters.

I-75 runs north-south through Knoxville, connecting the city to Chattanooga to the south and the Kentucky border to the north. North of Knoxville, I-75 passes through the communities of Campbell County and approaches Jellico at the Kentucky state line. South of the city, I-75 splits from I-40 near West Town Mall and continues through Farragut and Lenoir City before reaching the Sweetwater and Athens areas. The I-75/I-40 split junction on the west side is a critical monitoring point, as lane choice errors here send drivers in the wrong direction entirely.

Rush Hour and Traffic Patterns

Morning rush hour in Knoxville typically runs from 7:00 to 9:00 AM, with the heaviest congestion on the I-40/I-75 concurrency between the Papermill Road exit and the downtown I-40/I-275 junction. Westbound I-40 approaching the I-75 merge also backs up as commuters from east Knoxville and the Sevier County area head toward west Knoxville employers and the Oak Ridge National Laboratory corridor along SR-162 (Pellissippi Parkway).

Evening rush extends from approximately 4:00 to 6:30 PM, with the pattern roughly reversing. The I-40 eastbound corridor through downtown and the I-640 bypass both see heavy volumes as workers return to communities in east Knox County, Jefferson County, and Sevier County. Friday evenings are particularly congested in spring and summer, as tourist traffic bound for the Great Smoky Mountains National Park — America's most-visited national park — funnels through Knoxville on I-40 toward the Sevierville/Pigeon Forge/Gatlinburg corridor.

SR-162 (Pellissippi Parkway) serves as a key connector between I-40/I-75 in west Knoxville and communities to the south, including Alcoa and Maryville near McGhee Tyson Airport. This corridor is also the primary route for the thousands of employees commuting to Oak Ridge National Laboratory and the Y-12 National Security Complex. Morning and evening peaks on Pellissippi Parkway correlate closely with shift changes at these major federal facilities.

The University of Tennessee campus, located just south of downtown along the Tennessee River, generates its own traffic patterns tied to the academic calendar. Home football games at Neyland Stadium — with a capacity of over 100,000 — create extreme congestion on surrounding roads, I-40, and the Alcoa Highway (US-129) corridor. Game-day traffic should be monitored well in advance of kickoff.

Weather and Seasonal Conditions

Knoxville's location in the Tennessee Valley produces a humid subtropical climate with distinct seasonal effects on driving. Winter weather, while generally milder than cities further north, brings occasional ice storms and freezing rain that can shut down highways — particularly elevated sections of I-40 and I-640 overpasses. The surrounding mountain terrain means conditions can deteriorate quickly on routes toward the Smokies, even when Knoxville proper is clear.

Summer brings afternoon thunderstorms that can reduce visibility and create flash flooding on lower-lying sections of roadway. The Tennessee River and its tributaries run through the metro area, and heavy rain events occasionally close underpasses and low-lying connector roads. Fall brings the heaviest tourist traffic of the year as leaf-color viewers head toward the mountains, extending the typical weekend congestion period from late September through mid-November.
