The MTA is staggering the work to avoid more than once closure at a time on the same line.

“Replacing these elevators is long overdue and critical for reliable access to these unique ‘deep stations,’ and we’ve put together a schedule that takes care not to cause unnecessary inconvenience for customers,” said MTA New York City Transit President Andy Byford. “We thank our customers for their patience during this extraordinary work and hope they take advantage of the enhanced bus service and additional free transfers we’ve arranged for the duration of the projects.”
