Why all the 16 address lines are not act as a data lines in 8085 microprocessor?

the 8085 microprocessor is a 8-bit microprocessor and these are bidirectional but the address lines are unidirectional.these address lines are used to address the location of the instruction in memory .these data lines are used to transfer data between processor and peripheral devices. when the address of the instruction will be recognized by the address lines the data will be send to the processor

therefore the 16 address lines are not act as a data lines in 8085
