 between Gladstone and Rapid River in 1971 . The state built a new bridge over the Manistique River in 1983 , bypassing downtown . MDOT disposed of the former routing of US 2 into downtown in two ways . The western half was initially an unnumbered state highway until it was later transferred to local control . An extension of M ‑ 94 replaced the remainder , including the Siphon Bridge , through downtown . In that same year , the department truncated US 2 to end in St. Ignace by removing it from the I ‑ 75 freeway . The last changes were made to US 2 's routing through Iron River in 1998 , bypassing the bridge that formerly carried the highway over the river in town . In 2011 , MDOT raised the speed limit along the expressway section in Delta County from 55 to 65 mph ( 89 to 105 km / h ) , although the speed limit for trucks remains 55 mph ( 89 km / h ) .   = = Memorial designations and tourist routes = =   On July 1 , 1924 , the State Administrative Board named M ‑ 12 , the predecessor to US 2 in Michigan , the Bohn Highway to honor Frank P. Bohn , a prominent local citizen who later served in Congress from 1927 to 1933 . In 1929 , the residents of Escanaba created a memorial to the veterans of World War I called Memory Lane . The project consisted of elm and maple trees planted along US 2 / US 41 west of town . The American Legion sold the trees to local businesses and individuals who could honor specific soldiers . Later in 1949 , the Bessemer Women 's Club created a tribute in the form of a permanent living memorial to the area veterans . Also called Memory Lane , the group planted 140 elms and 1 @,@ 840 evergreens , trees and shrubs as a landscaped parkway along 2 @.@ 3 miles ( 3 @.@ 7 km ) of US 2 east of Bessemer .   Most of US 2 , along with US 23 in the Lower Peninsula , was designated the United Spanish War Veterans Memorial Highway in 1949 . To connect the gap in the routing where US 2 cuts through Wisconsin , M ‑ 95 and M ‑ 69 were used in place of US 2 between Iron Mountain and Crystal Falls . Signs marking the highway were not erected until 1968 when Governor George W. Romney had them installed .   The Amvets Memorial Drive designation was created for the section of US 2 / US 41 / M ‑ 35 between the northern Escanaba city limits and County Road 426 ( CR 426 ) in Delta County . The American Veterans ( AMVETS ) organization in Michigan petitioned the Michigan Legislature to grant this designation , which was assigned under Public Act 144 in 1959 .   Two sections of US 2 are part of the overall Great Lakes Circle Tour ( GLCT ) : the segment from the Wisconsin state line near Ironwood to the M ‑ 28 junction in Wakefield is part of the Lake Superior Circle Tour ( LSCT ) , and the segment from the southern M ‑ 35 junction in Escanaba to the eastern terminus in St. Ignace is part of the Lake Michigan Circle Tour ( LMCT ) . These two tours were created in May 1986 through a joint effort between MDOT and its counterparts in Wisconsin , Minnesota and Ontario . The section of US 2 between Iron River and Crystal Falls has been named the Iron County Heritage Trail . This Pure Michigan Byway was designated to honor the " rich history of two industries that built a state and nation : mining and logging . " On August 26 , 2007 , MDOT announced that the section of US 2 that runs concurrently with M ‑ 35 in Delta County was being included in the UP Hidden Coast Recreational Heritage Trail .   = = Historic bridges = =   There are six bridges along current or former sections of US 2 that MDOT has added to its listing of Michigan 's Historic Bridges ; two of these are also listed on the National Register of Historic Places ( NRHP ) . A third bridge added to the NRHP in late 2012 has not been added to MDOT 's listing however . The first of these historic bridges is the crossing of the Iron River , which has since been bypassed by a new bridge . The original structure , dating to 1918 , is a 55 @-@ foot @-@ long ( 17 m ) spandrel arch span that was built by the MSHD as Trunk Line Bridge No. 191 . The structure was listed on the NRHP on December 9 , 1999 , for its architectural and engineering significance .
