Everyone at this point knows that the bridge and the skate park will be torn down sometime this year but not everyone knows why...
The main reason is because it is falling apart and not safe to be under especially in conditions like these. Science can explain it better than us.
Deterioration of concrete from freeze thaw actions may occur when the concrete is critically saturated, which is when approximately 91% of its pores are filled with water. When water freezes to ice it occupies 9% more volume than that of water. If there is no space for this volume expansion in a porous, water containing material like concrete, freezing may cause distress in the concrete. Distress to critically saturated concrete from freezing and thawing will commence with the first freeze-thaw cycle and will continue throughout successive winter seasons resulting in repeated loss of concrete surface.
Regardless the bridge has been experiencing this since it was built in 1936 and is very dangerous at this point. Large sections of concrete are falling from above every time the temp rises above freezing.
Please be warned and do not park your vehicle under the bridge or even go there at all. No one is responsible except yourself if something happens. You have been warned...
