Larry Sengstock Says Doonella Bridge Traffic Will Be Watched As Schools Return

Noosa Council says the revised Doonella Bridge traffic arrangement has started better than the original detour, but chief executive Larry Sengstock has warned the real test will come as school traffic returns.

Sunshine Coast News reported that authorities opened a single lane of Doonella Bridge at Tewantin to alternating two-way traffic after widespread backlash against an earlier plan that sent westbound motorists on a detour via Beckmans Road. Noosa Council's media release page confirms two July 13 updates: one announcing two-way single-lane traffic through lights for the foreseeable future, and another saying council would continue monitoring conditions as the school term resumed.

Mr Sengstock said traffic flowed relatively well over the weekend, although there was some congestion at certain times. He said council's focus was on how the network performs once school traffic returns and that officers were prepared to make adjustments if needed. He also described the revised arrangement as no perfect solution, which is the honest frame for a bridge project that has to keep moving while protecting local access.

The bridge is a key connection between Tewantin and Noosaville. Noosa Council's project material says the Doonella Lake Bridge upgrade is intended to strengthen a 58-year-old structure and extend its life by another 50 years. The project involves major works while maintaining one lane of traffic, and council has warned that delays and congestion are still expected, particularly during peaks.

The public reaction shows how quickly construction staging can become a local economic issue. The original westbound diversion added time for commuters and raised concerns for Tewantin businesses worried about customer access. The change to signal-controlled two-way traffic gives residents a direct route again, but it does not remove the bottleneck. It simply shifts the problem from a long detour to managed queuing.

That may still be the better compromise. If traffic lights can keep both directions moving and avoid the worst diversion impacts, the upgrade can continue without forcing every westbound trip onto a longer route. But the school-term return will expose whether the arrangement can handle morning and afternoon surges, bus movements and local shopping trips at the same time.

Council's monitoring will need to be visible and practical. Residents will want to know whether queue lengths, travel times, bus delays and business access are being measured, not just observed. If the signals are adjusted quickly and information stays current, frustration may ease. If delays grow without clear communication, pressure will return for another rethink.

The episode also carries a broader lesson for Sunshine Coast infrastructure. Roads, bridges and town-centre links are ageing while population and visitor numbers keep rising. Renewal is necessary, but communities judge the work by what happens on Monday morning, not by the engineering rationale. A project that looks reasonable on a map can become unworkable if it pushes too much inconvenience onto one side of town.

For Tewantin and Noosaville, the next few days are therefore more important than the weekend trial. The bridge arrangement has survived its first test, but school traffic will decide whether the current fix holds or whether Noosa Council must make another change to keep the upgrade and the local economy moving together.
