Down-stream side of residential bridge
shows damage caused by high water.

Concrete structure was nearly washed
away, making the bridge unusable.

Floodwaters caused excess sediment
that had to be removed. 

The use of the original drain pipe was
incorporated into the new design.  

Internal steel mesh is prepared before
Shotcrete is applied.

Very little excavation was needed due to
the erosion caused by floodwaters.

Down-stream side of bridge shows
wing wall ready for Shotcrete.

Measures were taken to ensure that 
any future erosion was minimal.

This overhead application shows
just how versatile Shotcrete is.  

Not only is Shotcrete easier to place than
traditional concrete, it can also be stronger.

Secondary culvert is formed using
Shotcrete.

This additional culvert more than doubled
the flow capacity of the original drain pipe.

Substantial wing walls direct water
through culverts while minimizing erosion.

Final design allowed excess floodwaters
to pass over bridge without causing damage.
