In 1929, Allan Williams placed a picnic table on the side of the road along US 16 south of Saranac. Williams was the Ionia County engineer in charge of the various roads in the county, and that location is "what many consider to be the nation's first roadside table". The first change to the US 16 routing was made in 1933 when the highway was moved to bypass Farmington, with the old routing retained as a state highway. The next year, in 1934, M-126 was created between Nunica and Muskegon. In 1940, US 16 was rerouted to replace M-126, and the former route of US 16 between Nunica and Grand Haven was redesignated M-104. Two further changes during 1941–42 rerouted the western end in Muskegon to end at the car ferry docks. Previously, motorists had to navigate from the western end along other roads to the ferry connection to the rest of US 16 in Wisconsin. The second change routed Bypass US 16 (Byp. US 16) along 28th Street and Wilson (previously the South Beltline and West Beltline sections of M-114) in the Grand Rapids area. The US 16 designation was moved in 1953 to replace Byp. US 16 while the former routing through downtown Grand Rapids was redesignated Business US 16 (Bus. US 16).
