The western terminus of M-14 is west of Ann Arbor, at exit 171 on I-94. This is a partial interchange; only traffic from eastbound I-94 can access eastbound M-14, and traffic from westbound M-14 must follow westbound I-94. From this junction, M-14 runs northeasterly through suburban Scio Township. The freeway is bordered by residential subdivisions to the southeast and woodlands to the northwest. M-14 curves around to the east through an interchange that has ramps that connect Miller and Maple roads; the ramps connect to Maple Road through a pair of roundabouts. As it approaches the Huron River, the freeway has an interchange with Business US 23 (Bus. US 23); the two highways merge and run concurrently to the north over the river. Bus. US 23/M-14 then has an unusual right-in/right-out interchange that uses short connector roads to provide access to Barton Drive on the north side of the river. The freeway then continues north to an interchange with US 23. The business loop ends there, and M-14 turns eastward to follow the US 23 freeway around the north side of Ann Arbor.
