A modular tile for a walkway system interlocks with another tile to constrain movement of the interlocked tiles in all three-dimensions. The tile includes a male projection which may be tapered to provide lateral wings that are received in corresponding pockets of a female receiver of the other tile. The wings may include vertically-facing male stop surfaces that are engageable with vertically-facing female stop surfaces within the pockets. The male projection may further include a forwardly protruding ridge that is received in a corresponding groove of the female receiver of the other tile. The engagement of the stop surfaces of the wings and pockets, and the engagement of the ridge in the groove is such that the tiles are vertically interlocked with each other. The tiles may be configured to enable a pivotable interlocking connection while one tile remains on the ground.
