Traveling on Monroe Street going east and after crossing Broad Street you would arrive at the front door of the New County Courthouse, the old historic US Post Office building, the Federal Courthouse Plaza, Hemming Civic Plaza with City Hall at the north end of the plaza, and the new library. Closing Monroe Street, this condition would not be possible.
Adams Street (one way west) currently has two traffic lanes and one parking lane. Monroe Street (if opened as I proposed) would have two lanes with an island between it and Adams Street.
If you were traveling from the parking garage to the courthouse you would cross two lanes of traffic on Adams Street arrive at an island and cross two lanes(or one if preferred) traffic lane of Monroe Street. On the north side would be the new courthouse plaza and green.
Monroe Street in the umbilical cord that ties our civic buildings together. Monroe Street gives access to these buildings.
