Notes: * The termini and final length for Former M-182 reflect the beginning and ending of the route and its length as of the time of the route's cancellation on November 18, 1970, however...
  ** While the cancellation date for this route is shown as November 18, 1970, it likely was not referred to as M-182 within the Dept of State Highways for quite a few years—if not decades—prior to its decommissioning. However, this specific trunkline route remains a part of the highway system until late 1970 even though most sources don't label it as M-182 after the late 1930s. (See additional notes below for details.)

New! 2025-11       M-182 was a very short (three-tenths of a mile) connector route between M-21, the major highway between Grand Rapids and Holland, and M-114, the Grand Rapids Beltline System which was completed and opened to traffic in the Grandville area in 1932. This was because M-114, the Grand Rapids Beltline, did not directly intersect with M-21/Chicago Dr as it passed over it via a grade-separation along with the railroad line which paralleled Chicago Dr southwesterly from Grand Rapids toward Holland. The Wilson Ave connector simply served as a state highway connector route between the two major highways. If M-182 was independently signed as its own trunkline route in the field, it was likely only signed as such for the first few years of its existence. It was never shown on the official state highway map issued to the public by the State HIghway Dept, although several other very short trunkline routes were either similarly never included on the map or only made it onto the map in later years.
       Evidence that M-182 was not signed in the field includes:
  1. The stretch of Wilson Ave in Grandville betwen Chicago Dr and 28th St is only shown on internal State Highway Dept maps—the kinds which showed every state trunkline route designation, signed or not—through 1937 and, while the roadway itself remains on those maps until 1970, it is never again shown with a route designation. (A set of maps produced by the U.S. Bureau of Public roads [forerunner of today's Federal Highway Administration or FHWA] also issued a set of maps in 1937 showing M-182 in existence, although that, in and of itself, is not an indication the route was signed in the field, however.)
  2. No news stories in the print media of the day have yet been located referring to that portion of Wilson Ave with a specific state route number, even after extensive searching.
  New! 2025-11 The three-tenths of a mile of Wilson Ave in Grandville between Chicago Dr and 28th St remained a state trunkline route—signed or not—until late 1970 when numerous state highway route changes were being made in the region due to the completion of the area's freeway system. The I-196/M-21/Gerald R Ford Frwy was open and the last section of I-196 between Grandville and Holland was only four years from completion. Because of this, several existing trunkline routes in the Greater Grand Rapids area were cancelled and turned back to local control during that timeframe. Initially, both BUS M-21 along Chicago Dr in Grandville and Wyoming and through Grand Rapids as well as M-11 on 28th St and Wilson Ave were both earmarked for cancellation, however, M-11 was ultimately retained. Even so, with the impending transfer of BUS M-21/Chicago Dr to local control, the connecting route along Wilson Ave was no longer needed and was the first trunkline segment in the area ot be cancelled.
History: 1932 (Sept 15) New! 2025-11 – The State Highway Advisory Board recommends a total of 67 miles of new trunkline routes for inclusion in the state highway system, as well as the cancellation of 36 miles of "unused" routes, for a total net gain of 31 miles. Three-tenths of one of those miles reccommended for approval by the State Administrative Board is a short connector route into downtown Grandville.
  1932 (Oct 29) New! 2025-11 – Six weeks later, the 0.3-mile stretch of Wilson Ave in Grandville from M-21/Chicago Dr downtown northerly to 28th St at the end of a newly-opened segment of the M-114/Grand Rapids Beltline System is officially established as a trunkline route and given the M-182 designation.
  1937 New! 2025-11 – M-182 is last symbolized as such on internal State Highway Dept maps. After this point, departmental documentation indicates the route is considered as "part" of the segment of M-21 along Chicago Dr from the Ottawa/Kent Co line northeasterly to where it passes under M-114/28th St. If M-182 has been signed until now, from this point onward it is likely signed as "TO M-114" heading north from M-21/Chicago Dr and as "TO M-21" from M-114/28th St southerly.
  1970 (Nov 18) New! 2025-11 – With changing traffic patterns in the area and the future potentiality of the cancellation of BUS M-21 as a state trunkline route through Grandville, the 0.3-mile long trunkline connector along Wilson Ave between BUS M-21/Chicago Dr and M-11/28th St is cancelled as a state trunkline route and turned back to local control.
Controlled Access: New! 2025-10 No portion of former M-182 upon decommissioning existed as freeway or expressway.
