I have seen so many near misses with this underpass I walk away wondering why is this sign not enforced.
If they put someone their early morning and late afternoon to hand out fines for not walking the revenue would easily pay for the wages of the person they put their and then some.
When parents have to hold on to their children and tell them to walk by the wall so as to make sure they are not knocked over that is sad it is obvious that the solution they have at the moment is not working.
