ends there, and M-14 turns eastward to follow the US 23 freeway around the north side of Ann Arbor. The US 23/M-14 freeway runs for about before US 23 turns southward to run between Ann Arbor and Ypsilanti while M-14 continues east through Ann Arbor Township past Domino's Farms, the office complex for Domino's Pizza that was to be the home to Tom Monaghan's Leaning Tower of Pizza. East of that complex, M-14 runs through woodlands and fields north of the community of Dixboro. The freeway turns northeasterly after the interchange with M-153. At the Napier Road underpass, M-14 crosses into Wayne County. Once across the county line, the M-14 freeway runs through residential subdivisions from the western Detroit suburbs. There is an interchange for Beck Road and M-14 expands to six lanes, turning back to the east. The freeway crosses a rail line operated by CSX Transportation The freeway passes Ford Motor Company's Sheldon Road Plant near the Sheldon Road interchange. There is a crossing for another CSX rail line near the bridges over the River Rouge by the St. Johns Golf Course. The freeway through this area curves around a bit north of its previous course. As M-14 nears the Livonia city line, it meets an interchange with I-96 and I-275 that marks the eastern terminus of M-14 in Plymouth Township. M-14 is maintained by MDOT like other state highways in Michigan. As a part of these maintenance responsibilities, the department tracks the volume of traffic that uses the roadways under its jurisdiction. These volumes are expressed using a metric called annual average daily traffic, which is a statistical calculation of the average daily number of vehicles on a segment of roadway. MDOT's surveys in 2010 showed that the highest traffic levels along M-14 were the 86,500 vehicles daily east of the Sheldon Road interchange in Plymouth Township; the lowest counts were the 26,641 vehicles per day west of the Miller Road interchange. All of M-14 has been listed on the National Highway System, a network of roads important to the country's economy, defense, and mobility. History Previous designations In July 1919, M-14 was signed on a north–south route that ran most of the length of the Lower Peninsula, beginning at the Ohio state line south of Hudson to end south of downtown Cheboygan. It mostly followed the path of present-day US 127, I-75 and M-27. This edition
