Narrative:

Aircraft X was cleared to land in a busy arrival sequence. I was also working a busy departure sequence off a parallel runway. Aircraft Y was sequenced behind aircraft X. Because of the differences in performance I needed aircraft X to exit the runway as quickly as possible. Due to airport construction I was aware that getting it off the runway early would create a taxi conflict with aircraft Y after it landed. I would not be able to keep aircraft Y on the runway because of subsequent arrivals. I was trying to get aircraft X off the runway and explain he needed to expedite his taxi on the parallel taxiway. I misspoke and told him to exit at taxiway W2; when I meant taxiway W3. Taxiway W2 is a reverse high-speed with a same exit point as W3. Aircraft X; despite being at taxi speed; rolled past both. I was not aware of my bad instructions until I looked back after clearing another aircraft for takeoff. Aircraft X had roll past both taxiways W2 and W3. I told aircraft Y to go around. Aircraft Y was close enough in that it set off the asde-X.all the construction on the field makes for an extremely complicated operation that changes every day. The construction on taxiway M has made moving aircraft in and out of the airport's single FBO terribly difficult. I was worried more about the next issue in the sequence and not focused as much on the immediate need to get aircraft X off the runway; and so I misspoke while trying to make sure he didn't try to stop or slow down once he got off the runway. This was a case of putting the cart before the horse.

Title: A Tower Controller reported issuing the wrong taxiway to an aircraft to exit the runway. The aircraft did not exit the runway at the wrong taxiway or the intended taxiway causing a subsequent arrival to be issued go around instructions.
