Work will be done sometime between 2012 and 2015!
We will work with the city to build in some scheduling
flexibility
We will coordinate closely with the affected agencies to minimize disruptions to the
City and its citizens
We apologize in advance for some inconveniences you will undoubtedly endure – but not for the increased safety you
will gain
