Reinforced-concrete twin-cell box-culvert crossing and channel diversion.
The challenge
Relieve flooding on an industrial access road by enlarging a crossing — while keeping the channel flowing and the road open.
Our approach
We built a temporary diversion, cast the twin-cell box culvert in stages off-line, then switched flow and reinstated the road over the new structure.
The outcome
Flood capacity restored to design standard with the access road reopened and the channel stabilised.
