with 32 others, underwent a complete overhaul as part of the Enhanced Station Initiative. Updates included cellular service, Wi-Fi, USB charging stations, interactive service advisories and maps, improved signage, and improved station lighting. In January 2018, the NYCT and Bus Committee recommended that Judlau Contracting receive the $125 million contract for the renovations of 57th and 23rd Streets on the IND Sixth Avenue Line; 28th Street on the IRT Lexington Avenue Line, and 34th Street–Penn Station on the IRT Broadway–Seventh Avenue Line and IND Eighth Avenue Line. However, the MTA Board temporarily deferred the vote for these packages after city representatives refused to vote to award the contracts. The contract was put back for a vote in February, where it was ultimately approved. The subway station was closed for renovations on July 23, 2018, and reopened slightly ahead of schedule on November 29, 2018. Access to the PATH station was retained during the renovation via the street stairs on the southern side of the station, which are owned by the Port Authority; hence, those entrances were not renovated. Station layout This underground station has two tracks and two side platforms. No crossover, crossunder or mezzanine exists to allow a free transfer between directions. The PATH tracks, which were built 40 years before the Sixth Avenue Line, are behind the trackway walls where there would typically be the express tracks would be. The Sixth Avenue PATH tracks are on top of the express tracks used by the B and D, which were constructed in the mid-1960s using a "deep-bore" tunneling method and both sets of tracks are not visible from the platforms. A green trim line with a darker green border runs along both track walls, and appears to be obscured by support beams directly underneath 23rd Street. A similar trim line is present on the platforms walls, though is higher and thus is regularly obscured by the angled ceiling supports. The platform walls also have mosaic name tablets reading "23RD STREET" in white sans serif lettering on a dark green background and lighter green border. Small tile captions reading "23" in white lettering on black run below both trim lines. On the express tracks on the lower level, the deep-bore tunnel's round shape becomes square below this station and at 14th Street, where provisions for lower level platforms were built.
