The language seems rather confusing.
The previous notice issued yesterday, at bottom, indicated nightly closures of Sixth "Thursday May 28th to Friday May 29." That word "to" indicates that the closure ends today, while the word "closures" indicates multiple days. Rest assured, as the updated notice directly below indicates, the street will be closed tonight from 10 pm to 6 am.
The new work announced will be 8 am to 4 pm Saturday, May 30 and Sunday, May 31. The notice states that "Sixth Ave will be open during this weekend, however surrounding work zones will be closed."
That's unclear. If there are work zones, they are "open" and "operating", thus taking up the street. If they are "closed," that could leave the impression that they're idle.
