Tennessee Department of Transportation spokeswoman BJ Doughty attributed the delay in the project completion to a wet spring that held up repairs under the bridge and badly deteriorated concrete.
The project was estimated to cost $1.1 million. Doughty said Thursday that it is unclear how much it ended up costing.
"Since the job was just completed the estimated amount has not yet been paid," she said. "It will take some time to see if the job came in over or under the budget."
The project was to repair the two bridges on Northwest Broad Street, a main thoroughfare. Both were several decades old and had not undergone any major repairs since their construction.
"We have extended the lives of the bridges by several years," Doughty said. "Should these repairs not have been made, we could have been looking at a major replacement project in the future that would've taken 18 to 24 months to complete rather than the six months this took."
