1. Ice bomb and de-icing solution

2. Ice being accumulated on the
cables spanning the new Port
Mann Bridge started falling as
deadly “ice bombs” onto the
deck and cars on the bridge.

WE NEED A SOLUTION NOW >>>>>

3. Many expensive solutions were thought out such as cable sweepers
and hydrophobic coatings.
However, they were expensive and unpractical.

4. We have come up with “The Right Solution.”
Proposal:
To use custom heated coils that wraps around the
cables of the bridge that span over the bridge deck to
avoid freezing and build up of snow and ice. The
coils will be powered by electricity running through
the bridge the same way the street lights are lit up.
With this less expensive method, we do not have to
close off the entire bridge when installing the coils.

5. Black Coil :
Wraps around the bridge
cable and releases heat to
avoid freezing and ice
accumulation

The heating coils will be turned on when there is snow or the
weather drops below two degrees Celsius.
