Loud bangs to be heard from testing project on the Muddy River starting Tuesday

A testing project on the Muddy River will involve short, loud bangs that will sound similar to a gunshot starting Tuesday, says the US Army Corps of Engineers. The construction, which is part of the $30.9 million Muddy River Flood Risk Management and Environmental Restoration project in Boston, will be done three times every other day, about 15 to 30 minutes apart, said the agency. The testing is to determine the depth needed to create support shafts for later developments and is expected to be completed by May 10, the Army Corps said.
