Current plans, however, have the Second Avenue platform to be built below the current one, though a free transfer will still be provided. The "Deep Chrystie Option", as the selected proposal is called, would instead place the Second Avenue Subway platform below the Sixth Avenue Line tracks, to create the least amount of community disturbance by utilizing tunnel boring machines. Cut-and-cover methods would be utilized only at the station site. The current platforms would be widened to create space for staircases to a new intermediate mezzanine between the two levels. This new mezzanine level will also include a new fare control area with staircases, escalators and elevators leading to two new station entrances/exits, with one on either side of Grand Street between Chrystie and Forsyth Streets. Although the Second Avenue Subway platform and the new entrances/exits would be ADA accessible, it is currently unknown if the Sixth Avenue Line platforms will also become ADA accessible. However, the widening of the platforms and additional entrances would likely trigger ADA requirements for adding elevators. To the north of the station, the Second Avenue Subway tunnels would curve to travel under Sara D. Roosevelt Park rather than directly below the Sixth Avenue Line tunnels under Chrystie Street, to avoid steel piles and other obstructions dating from the construction of the Chrystie Street Connection. To the south, the unused tunnel between Pell and Canal Streets could be used as an ancillary facility with the new passenger-service tunnels located beneath and slightly to the west.
