Narrative:

B757 was instructed to taxi to runway 8R (out of spot 6) via Y1, Y, M. B757 was observed on runway 8R between M4 and M5 with a B190 holding in position for takeoff. B757 was instructed to exit runway at M4. Possible contributing factors: taxiway Y is closed between txwys north and M and aircraft have to make 2 turns to join taxiway M. Intersection N5 signage is confusing and labeled 'west.' taxiway north has been closed for months between hh and taxiway Y, forcing outbound aircraft to taxiway M. Taxiway Y3 has been closed daily. Y1, Y2 and Y3 are confusing to pilots. Taxi instructions issued did not alert pilot that they had to transition from taxiway Y to taxiway north to taxiway M. Ground frequency 121.8 was OTS. Supplemental information from acn 634417: ground control cleared us Y1, taxiway M, to runway 8R. We taxied out of spot 6, along Y1 when we both confirmed the clearance between ourselves as taxiway M to runway 8R. We also confirmed between us that taxiway M was the outer parallel taxiway from the ramp. As we taxied by the ramp construction area we looked for the second (outer) parallel. Not realizing that taxiway north was closed at that point (Y1), we crossed taxiway M at M6 onto runway 8R thinking it was taxiway M. We immediately realized that this 'did not look right,' and exited at M4. Page 10-8 was referenced as we were taxiing out.

Title: MIA GND CTLR ISSUES TAXI INSTRUCTIONS TO A B757 CREW TO RWY 8R THAT AVOIDS A CONSTRUCTION AREA BUT CAUSES THE PLTS TO BECOME CONFUSED AND TAXI ONTO AN OCCUPIED RWY.

Narrative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

Mia ground controller issues taxi instructions to a B757 crew to runway 8R that avoids a construction area but causes the pilots to become confused and taxi onto an occupied runway.
