Narrative:

Inbound on the arrival; we were told to expect runway xyr; which we had briefed at altitude prior to descent. The weather was [VFR]. We had the field in sight passing over downtown.inside the FAF on a visual approach runway xyr; tower asked if we would like to land on runway xyc. We agreed to land on runway xyc and the pilot flying (PF) lined up on [a] taxiway; thinking it was runway xyc. As the pilot monitoring (pm); I also looked out and assumed that we were lined up on runway xyc. We expected an unusual sight picture since 16C had just been opened after having been re-surfaced. The PF said not to worry about changing things in the box since he was lining up visually. I did; however; put in the ILS frequency for runway xyc in the PF side as back-up. The flight director then showed us to be on glide-slope but off course. In-close the localizer disappeared and only the glideslope portion of the flight director remained. Since I had visually confirmed our intended landing surface; which we assumed to be xyc; I tried to figure out why the localizer information was off; since I had not remembered any notams to that effect. Approaching 500 feet I focused my attention on monitoring the flare and landing. Upon landing the tower informed us that we had landed on [a] taxiway; which; by that time; was clearly evident to all.
