Traffic congestion is anticipated to increase in the area, particularly during peak times, and we advise motorists to allow extra travel time or take an alternative route if possible. We sincerely apologise for any inconvenience caused during this time.

Noise, dust, and vibration may be noticeable to those living or working nearby, as we prepare for construction of the new bridges, freeway on and off-ramps and the shared path. A range of control measures are being put in place to minimise dust and noise disturbance.
