Human Factors; Procedure
I had just opened Local East 1 at the start of the day shift. I was briefed on closures which included taxiways M3; M4; M5; EL between RWY 17R and RWY 17C and M between M3 and M5. I cleared Aircraft X to land on Runway 17C and advised him of the taxiway closures and asked that he plan to exit at M6. I then cleared Aircraft Y to land and advised them to plan the same exit. On landing; Aircraft X advised that M6 was coned off and not usable. I sent Aircraft Y around ; but noticing that they may have touched down and seeing that enough of Aircraft X appeared to be on the un-coned portion of M6; advised Aircraft Y to disregard. Aircraft Y did go around. DFW Airport Authority said that M6 was closed and they just forgot to tell us.
DFW Tower Controller reported a runway incursion with two arrivals on the same runway.
