Work on a new bridge at Amamoor, south of Gympie, will start next week, ensuring better access during flooding.
The old wooden bridge over Amamoor Creek will be replaced by a new two-lane concrete structure costing more than $2 million.
Gympie councillor Julie Walker says it will improve access for local residents and the thousands of people attending the annual Gympie Music Muster.
"There have been a few accidents off that bridge," she said.
"It is a one lane [bridge] so we ... had to put rumble strips in [a while] ago to ... slow traffic down because there is a nice long stretch leading up to it but in the future it'll be a much safer bridge as well as when there's a flood on, it won't be damaged every time like it has been in the past."
She says the old bridge is unsafe and was regularly damaged during flooding.
"With logs coming down and hitting against it and knocking pieces off," she said.
"So concrete is a lot more durable, it will last a lot better and takes a fair size flood to put it up over the bridge anyhow but when it does it'll be a lot more secure."
