Geotech Tests at Nottely Dam to Cause Lane Closure
March 24, 2013
UNION COUNTY, Ga. ─ Motorists can expect lane closures on the road over Nottely Dam beginning April 1 and continuing for several weeks as the Tennessee Valley Authority conducts a geotechnical evaluation of the earth-and-rock structure as part of a “health check” update of all 49 dams in the TVA system.
TVA’s dams are safe, and the health check is part of a continuous improvement campaign to make sure TVA’s dams meet today’s stringent industry safety standards.
As part of the Nottely health check, TVA anticipates that core drilling from the roadway on the crest of the dam, Georgia State Route 325/Nottely Dam Road, will require lane closures in sections on the dam and up to a mile west of the main dam.
Completed in 1942, Nottely Dam is 197 feet high and stretches 3,915 feet across the tributary Nottely River, providing flood storage and hydroelectric generation to TVA.
- Multiple segments of the west-bound lane will be closed for the duration of the project.
- Temporary traffic signals will be in place on both ends of the closure zone to allow traffic to move through the section (one direction at a time).
- A reduced speed limit of 25 miles per hour will be enforced within the closure zone.
- The limits of the closure zone will be shifted at times through the duration of the project. Motorists need to be watchful for revised closure locations.
- In certain cases, traffic will be stopped briefly in both directions to allow construction vehicles to maneuver within the work zone.
- In certain cases, a flagman may replace the temporary signals and manual traffic control may be utilized.
Motorists are urged to watch for construction workers and equipment, to be cautious and to drive slowly through the work zone. All scheduled work is subject to change depending on weather, geotechnical conditions encountered and other factors beyond the control of the Georgia Department of Transportation, TVA or engineering contractor Stantec.
The Tennessee Valley Authority is a corporate agency of the United States that provides electricity for business customers and local power distributors serving 9 million people in parts of seven southeastern states. TVA receives no taxpayer funding, deriving virtually all of its revenues from sales of electricity. In addition to operating and investing its revenues in its electric system, TVA provides flood control, navigation and land management for the Tennessee River system and assists local power companies and state and local governments with economic development and job creation.
