A few people have asked about this in comments, based on this original post, so here is an update from the folks at the Department of Design and Construction:

Work will continue on West Broadway between Thomas and Leonard streets until the spring 2024. When test pits were being dug during excavation, it was determined that the old water mains dating back to the 1800s needed to be replaced to accommodate the combined sewer replacement and prevent any water main breakage.

Within the next two weeks work will move towards the west side (in front of 60 Hudson, which will soon remove its sidewalk shed with the completion of the repointing and window replacement work) to continue the water main replacement work. After the water mains have been replaced, then the combined sewers will be replaced.

The project area will remain within those two blocks.
