A long-term closure of the northeast 4th and Hill Street portal at Pershing Square starts next Monday, April 18, through January 2017. During the closure, crews will replace the escalators and re-grade the Metro plaza on that side of the station. In addition to escalator replacement, the closure will coincide with a longer-term project — the construction of a mixed-use development.
The 4th Street west entrance and 5th Street entrance to Pershing Square Station will remain open for use.
Here’s the construction notice:
