Safety First? Or Last?

This is one of two signs on north side of the 500 block of Warren Street trying to get pedestrians to cross the street to avoid walking in the street in front of the blocked sidewalk in front of City Hall.  The sign hasn't been near the sidewalk or helpful to pedestrians for at least 2 months (not that anyone was paying attention to it to begin with).  The sidewalk in front of City Hall has been closed off since early March.

Meanwhile, once again this morning, I saw no work taking place by the contractor to replace the missing sidewalk in front of City Hall.
