Tennessee River Gorge

The Marion Memorial Bridge was a 4-span metal truss bridge that formerly carried U.S. Route 41 in Marion County, Tennessee over the Tennessee River and Nickajack Lake. It was built in 1929. The main span was 369 feet (112 m), and the bridge had a total length of 1,870 feet (570 m). The bridge was listed on the National Register of Historic Places on October 25, 2007. The bridge featured an unusual truss configuration that is a hybrid of the Parker and K-Truss configurations. The bridge was replaced by a new concrete and box girder span that opened in November 2014, slightly delayed from its target completion date of August 2013 by conditions encountered in the construction of the replacement bridge footings. Since the construction of the new bridge's footings involved blasting within 30 feet (9.1 m) of the Marion Memorial Bridge, state officials closed the bridge to vehicle and pedestrian traffic on January 9, 2012, with traffic being re-routed to the Interstate 24 bridge south of the span. The metal trusses of the bridge were demolished and removed by June 2015. The bridge was delisted from the National Register in June 2016. Some people in the community expressed the desire to preserve the bridge in some way. Tennessee Department of Transportation officials said the bridge was costly to maintain, citing as an example the repainting cost of $1 million.This bridge was built before the construction Nickajack Dam, a few miles downriver. The higher mean pool of the new reservoir necessitated raising the bridge from its original height. A bridge of similar design in Meigs County, Tennessee, that carried Tennessee Highway 58 across the Hiwassee River was imploded in November 2007, along with another similar bridge that carried Highway 58 over the Tennessee River in Roane County.

Haletown (also known as Guild) is an unincorporated community in Marion County, Tennessee, United States. It is part of the Chattanooga, TN–GA Metropolitan Statistical Area. Haletown is probably best known as the former location of Hales Bar Dam, a major hydroelectric project completed in 1913 by the former Tennessee Electric Power Company (TEPCO) and as a prominent location along the Tennessee River at Nickajack Lake.

Hales Bar Dam was a hydroelectric dam once located on the Tennessee River in Marion County, Tennessee, United States. The Chattanooga and Tennessee River Power Company began building the dam on October 17, 1905, and completed it on November 11, 1913, making Hales Bar one of the first major multipurpose dams and one of the first major dams to be built across a navigable channel in the United States. It began operation on November 13, 1913. On August 15, 1939, the Tennessee Valley Authority, which had been established by the President Franklin D. Roosevelt administration to develop and regulate flood control and hydropower in the Valley, assumed control of Hales Bar Dam after purchasing TEPCO's assets through Eminent Domain. It had conducted a lengthy court battle that went all the way to the US Supreme Court. The TVA worked for two decades trying to fix a leakage problem that had plagued Hales Bar since its construction. But, after continued leakage and determining that expanding the dam's navigation lock would be too expensive, TVA decided to replace the dam. It built Nickajack Dam 6 miles (9.7 km) downstream. Hales Bar Dam ceased operation on December 14, 1967.

Nickajack Lake is the reservoir created by Nickajack Dam as part of the Tennessee Valley Authority. The lake stretches from Nickajack Dam to Chickamauga Dam, passing through the city of Chattanooga. The Tennessee River Gorge, commonly referred to as the "Grand Canyon of Tennessee", is also part of Nickajack Lake. Full pool for Nickajack Lake is approximately 633.5 feet (193.1 m) above sea level, and remains consistent during the course of the year, unlike nearby Chickamauga Lake. The world record for freshwater drum was caught from Nickajack Lake in 1972 by Benny Hull, and weighed in at 54 pounds 8 ounces (24.7 kg). A lake sturgeon was caught in Nickajack Lake in 2011. This was the first sighting of one in the lake since they left the area in the 1960s.

Nickajack Dam is a hydroelectric dam in Marion County in the U.S. state of Tennessee. It is one of nine dams on the Tennessee River owned and operated by the Tennessee Valley Authority, which built the dam in the mid-1960s to replace the outdated Hales Bar Dam 6 miles (9.7 km) upstream. The dam impounds the 10,370-acre (4,200 ha) Nickajack Lake and feeds into Guntersville Lake. Nickajack Dam is named for a Cherokee village once located just upstream from the dam (the site is now submerged). The village was the namesake for Nickajack Cave, which was partially flooded by the reservoir.
