[Updated] Jackhammers in tow, city workers investigate the Mystery Puddle of Avenue A

Uh-oh! There just might be something to that Mystery Puddle in the southbound lane of Avenue A at Sixth Street. 

Goggla reports that jackhammer-toting city crews are currently on the scene digging a hole under the East Spillage. (H/T Ade!) 

Hopefully, whatever the workers find won't lead to months of excavation and metal street plates like we've seen on Seventh Street and First Avenue. 

For now, though (brace), we may have seen the last of the Sixth Street Seaport. (H/T Molly!)

Updated 6 p.m. 

Work appears to be done for the day...

Should only have about another 4-5 months of work left here!
