PTH 16A runs in concurrence with PR 262 from its southern terminus into Minnedosa,^[1] using 1st Street S.W., 3rd Avenue S.W., and Main Street within the town limits before PR 262 leaves the concurrence at 2nd Avenue S.E.^[2]

PTH 16A continues along Main Street before meeting westbound PR 355 (6th Avenue N.W.) at the north end of the town.^[3] The highway leaves Minnedosa after passing PR 355 and starts transitioning to an east-west route for 1.5 kilometres (0.93 mi) as it climbs out of the valley, completing the transition once it reaches the top.^[4] From this point, PTH 16A continues for 3.5 kilometres (2.2 mi) to its western terminus with PTH 16 and PTH 10.^[5]

The speed limits for PTH 16A are as follows:

• 90 kilometres per hour (56 mph) from PTH 16/PR 262 to Minnedosa
• 70 kilometres per hour (43 mph) as the highway approaches Minnedosa's southern limits
• 50 kilometres per hour (31 mph) within the town of Minnedosa
• 80 kilometres per hour (50 mph) from PR 355 to the top of the valley
• 100 kilometres per hour (62 mph) from the top of the valley to PTH 16/PTH 10

Prior to 1971, PTH 16A was designated as a shared concurrence of PTH 4 and PTH 10. PR 262 was added to its current portion of the route when the Government of Manitoba implemented its secondary road system in 1966.

The Minnedosa by-pass was completed and opened to traffic in 1971, with the PTH 4/10 designation being transferred to the new highway.^[6] The old highway was re-designated as PTH 4A and kept that designation until 1977, when it was given its current number to coincide with the renumbering of the Manitoba portion of the Yellowhead Highway from PTH 4 to PTH 16.
