60-year-old bridge slated for repairs

Yarnell Road in deep West Knox County will be partially closed starting Friday, July 10, for bridge repairs that could take up to six months.


The almost 60-year-old bridge, which spans 27 feet over Hickory Road, sits just east of Everett Road.

The Tennessee Department of Transportation inspects and evaluates all Knox County bridges every two years and recently downgraded Yarnell Road from “fair” to “critical.” Bridges are classified as good, fair, poor, serious or critical. State officials said the settlement in the bridge deck – built in 1966 – indicates that the supporting beam has begun to lose structural integrity.

“The type of beam used in this bridge is common for bridges built at this time and this one deteriorated very quickly,” said Engineering and Public Works Director Jim Snowden. “It isn’t used anymore because it is very problematic for failure.”

The Engineering Department put aside $500,000 in the current FY21 budget for bridge repair. The project will cost about $250,000.

The county set up an easy detour that routes motorists from Buttermilk Road to Marietta Church Road.

“We don’t anticipate a lot of inconvenience by this closure and detour as the traffic volume on the road over the bridge is only about 2,000 cars per day,” Snowden said.

The repairs entail removing the bridge deck and structural beams before a new beam structure is placed and a new deck poured.

“The engineering team working on this bridge is incredibly knowledgeable and capable,” said Mayor Glenn Jacobs. “I know they will work as efficiently as they can to ensure that this bridge is safe for traffic as quickly as possible.”
