as the U.S. Route 64 Bypass and the State Route 40 Bypass after construction began on the extension. In 1982, after TDOT modified the highway numbering system for state highways, the SR 40 Bypass was replaced with SR 311. US 74 was added to the route in 1986. This route, however, remains largely unsigned. Traffic hazards In 1973 a four-way intersection with Varnell Road, located at the bottom of the steep downgrade on the western slope of Candies Creek Ridge was reconstructed with an overpass after many accidents, including one with fatalities, occurred immediately after being opened to traffic. Prior to construction, the then-incumbent superintendent of the Bradley County Road Department had reportedly requested TDOT to make this change to the design, but they had refused. Other portions of the road, including interchanges, have also received criticism as being hazardous and poorly designed. Recent developments APD-40 was designated as "Veterans Memorial Highway" by the Tennessee General Assembly in 2007. In May 2013, the Tennessee Department of Transportation (TDOT) began a project to rework the interchange with I-75. The original route narrowed at the interchange, and crossed the interstate on a two-lane bridge. The project was declared complete on December 16, 2015. The old bridge was replaced with a six-lane bridge, and the ramps were rebuilt and widened, with turn lanes added. Construction began on a new interchange with the newly constructed Cherokee Gateway located about midway between I-75 and South Lee Highway in 2015. The interchange had been proposed since at least 2009, and connects to what is now an industrial park. It was completed in May 2017 and was named in honor of Cleveland's mayor Tom Rowland. In 2016, the parallel bridges across 20th Street, the railroad, and Overhead Bridge Road were designated as the Dustin Ledford Memorial Bridge in honor of a man who was killed by an intoxicated driver near the Overhead Bridge Road exit.
