Metropolitan Parkway or Metro Parkway is a major thoroughfare in Metro Detroit that stretches west from Lake St. Clair Metropark to Bloomfield Township. Metro Parkway corresponds to 16 Mile Road in Metro Detroit's mile road system, and is sometimes referred to as such by area residents, but it is rarely officially called 16 Mile. It is only called Metro Parkway in Macomb County, and is known as Big Beaver Road and Quarton Road in Oakland County. Route description At its start, Metro Parkway is a four-lane divided expressway with signalized intersections at major roads, but very limited access from side streets. The east end of Metro Parkway is in Harrison Township at the main entrance to Lake St. Clair Metropark, at an intersection with Jefferson Avenue. Two miles to the west, Metro Parkway meets Interstate 94 at a partial cloverleaf interchange, and then crosses the Clinton River and enters Clinton Township. There, Metro Parkway widens to six lanes, and is joined by a frontage road, Nunneley Road, on either side, before an intersection with Gratiot Avenue. It crosses the Clinton River again as it enters Sterling Heights. After crossing the river, Metro Parkway passes the Freedom Hill County Park. It becomes a more standard divided highway at the Schoenherr Road intersection, with business and side streets along the corridor. After it crosses Van Dyke Avenue, Metro Parkway passes Chrysler's Sterling Heights Assembly plant, before a short overpass carries the road over a railroad track. A frontage road runs at-grade alongside the overpass, providing access to the Chrysler plant and other businesses between Van Dyke and Mound Road. The road then passes the Detroit Free Press/Detroit News printing plant, and continues west as Metro Parkway for another two miles. Upon crossing Dequindre Road, the Macomb-Oakland County border, Metro Parkway enters Troy and its name changes to Big Beaver Road. Big Beaver initially runs through a residential area, but the corridor progressively becomes more commercialized as it approaches I-75, with strip malls on either side at the Rochester Road intersection. High-rise office buildings, including the PNC Center, dominate the landscape by the time Big Beaver crosses Livernois Road. The three-mile segment of Big Beaver between Rochester Road and Coolidge Highway forms Troy's central business district, and is one of the busiest corridors in Oakland County. Half a mile west of Livernois, Big Beaver meets Interstate 75. The junction with I-75 was previously
