Workers Divert Sinkhole Hazard in Lynn

sinkhole sinkhole

Residents of the town of Lynn were advised last month to use caution when traveling. A large sinkhole that was blocking traffic at the intersection of Shepard and South Common streets has been repaired, and concrete barriers were strategically placed to avoid a hazard.The extra precaution was due to a broken sewer main near the collapsed road. There is a commonality in many nearby areas, as the sewers become inundated with heavy rain, there is a likelihood of sewer overflow.  In this case, the collapse also stems from the pipeline being over 100 years old. The Lynn Water and Sewer Department effectively repaired the piping, which was made of brick, with new brick and concrete.  Part of the rehabilitation included removing the dirt and other debris that caved into the sewer.  After the repairs were completed on the pipeline, the construction company was able to begin filling in the sinkhole.  The sinkhole was backfilled with stone and sand.  The area was then compressed with a tamper machine. The piping that needed replacement was made of red sewer brick from the late 1800’s.

Interesting Fact: The Boston University Bridge on Commonwealth Avenue has the distinct recognition of being the only place on the planet where a boat can sail under a train going under a car that is driving under an airplane.
