Starting on March 2, 1998, the tunnel was reconstructed along with the cracked tunnel floor. This was done to correct a major water problem that had existed for many years due to the presence of the Harlem Creek and other underground streams, which caused extensive flooding, water damage, and seepage problems that occasionally contributed to severe service disruptions. The project cost $82 million and was finished on October 12, 1998. During the reconstruction, many trains were rerouted via the IRT Lexington Avenue Line, while the trains were rerouted to the 137th Street–City College station on the IRT Broadway–Seventh Avenue Line. Each of the two Lenox Avenue Line tracks were alternately taken out of service and supplemental shuttle bus service connecting to other lines in the area were provided for much of this time. Station layout The station has two tracks and two side platforms. The 2 and 3 trains stop here at all times. The platforms were originally long, as at other stations north of 96th Street. The platform extensions are at the north ends of the original platforms. Fare control is at platform level. There are no crossovers or crossunders between the two side platforms to allow free transfer between directions. Design As with other stations built as part of the original IRT, the station was constructed using a cut-and-cover method. The tunnel is covered by a "U"-shaped trough that contains utility pipes and wires. The bottom of this trough contains a foundation of concrete no less than thick. The platforms consist of concrete slabs, beneath which are drainage basins. The original platforms contain circular, cast-iron Doric-style columns spaced every , while the platform extensions contain I-beam columns. Additional columns between the tracks, spaced every , support the jack-arched concrete station roofs. There is a gap between the trough wall and the platform walls, which are made of -thick brick covered over by a tiled finish. The original decorative scheme consists of blue tile station-name tablets, pink tile bands, a green terracotta cornice, and dark blue terracotta plaques. The mosaic tiles at all original IRT stations were manufactured by the American Encaustic Tile Company, which subcontracted the installations at each station. The decorative work was performed by tile contractor Manhattan Glass Tile
