Rock Blasting Could Cause Short Traffic Delays

You may experience some delays if you drive near the construction site for the Combined Sewer Overflow project construction near Monroe and Post Street. Due to large rocks underground, rock blasting will begin Monday, May 9 and last for approximately two to four weeks. Cars and pedestrians will be stopped from entering near the excavation location for up to 10 minutes at a time when blasting is underway. 

There will be flaggers on site to control traffic and signs and traffic control devices will alert drivers about the upcoming work.

Before the controlled blasting begins, there will be a series of whistles as follows:

·         Five (5) long air horn signals to indicate five (5) minutes until the blast
·         10 short air horn signals to indicate one (1) minute until the blast
·         Then the blast occurs
·         One (1) long air horn signals to indicate that the area is clear

It is anticipated that there will not be any notable vibrations that will occur as a result of the blasting.  Due to the drilling work for the rock excavation, it is anticipated that the noise level may be slightly higher than normal in the area.
