M-45 (Michigan highway)

Lake Michigan Drive starts near Lake Michigan at an intersection with Lakeshore Drive near the Grand Rapids water filtration plant. The road runs east to an intersection with US 31 in Agnew, where the M-45 designation begins. The area is marked by a mix of woodland and agricultural properties. The road runs through rural Ottawa County to Allendale. Through town, Lake Michigan Drive widens to a four-lane divided boulevard with a median. East of the main part of town, M-45 passes the main campus of Grand Valley State University before crossing the Grand River. At 24th Avenue, the highway loses its median and gains a central turn lane. The landscape becomes more suburban as the highway crosses into Kent County near the M-11 intersection in Walker. From here east to the terminus in Grand Rapids, the road is lined with residential subdivisions and commercial properties. At Bridge Street, Lake Michigan Drive turns to the southeast and approaches John Ball Zoological Garden. M-45 ends at the interchange with I-196. Lake Michigan Drive continues east to its end where it becomes Pearl Street near the Grand River downtown.{{cite MDOT map |year=2010 |section=K8}}{{google maps |url=https://maps.google.com/maps?f=d&source=s_d&saddr=M-45+E%2FLake+Michigan+Dr&daddr=W+Fulton+St%2FLake+Michigan+Dr+NW&hl=en&geocode=FfazjwId7_jc-g%3BFbaajwIdE0Tk-g&mra=ls&sll=42.966127,-85.835452&sspn=0.029362,0.029097&ie=UTF8&t=h&z=10 |title= Overview Map of M-45 |access-date= February 25, 2011}}

The Michigan Department of Transportation (MDOT) maintains M-45 like all other parts of the state trunkline highway system. As part of these responsibilities, the department tracks the volume of the traffic using its roadways which is expressed using a metric called average annual daily traffic (AADT). This is a calculation of the traffic levels for a segment of roadway for any average day of the year. In 2009, 4,910 vehicles used the section of M-45 near the western terminus daily. Near the interchange with I-196, 32,376 vehicles were observed along Lake Michigan Drive each day.{{cite web |author= Bureau of Transportation Planning |url=http://mdotnetpublic.state.mi.us/tmispublic/ |title= Traffic Monitoring Information System |publisher=Michigan Department of Transportation |date=2008 |access-date=February 25, 2011}} No segment of the highway is listed on the National Highway System,{{cite map|author=Michigan Department of Transportation |location=Lansing |title=National Highway System, Michigan |date=April 23, 2006 |publisher=Michigan Department of Transportation |url=http://www.michigan.gov/documents/MDOT_NHS_Statewide_150626_7.pdf |format=PDF |access-date=October 7, 2008 |url-status = dead |archive-url=https://web.archive.org/web/20121004040152/http://www.michigan.gov/documents/MDOT_NHS_Statewide_150626_7.pdf |archive-date=October 4, 2012 |df= }} a network of roads important to the country's economy, defense, and mobility.{{cite web |first1= Stefan |last1= Natzke |first2= Mike |last2= Neathery |first3= Kevin |last3= Adderly |url= https://www.fhwa.dot.gov/planning/national_highway_system/ |title= What is the National Highway System? |work= National Highway System |publisher= Federal Highway Administration |date= June 20, 2012 |access-date= July 1, 2012 |name-list-style=amp}}

M-45 was originally designated in the UP on what is now M-95 by July 1, 1919. The highway ran between M-12 in Sagola and M-15 in Humboldt Township.{{cite MDOT map |date= 1919-07-01U }} When the United States Numbered Highway System was created on November 11, 1926,{{cite map |author1= Bureau of Public Roads |author-link= Bureau of Public Roads |author2= American Association of State Highway Officials |author2-link= American Association of State Highway Officials |date= November 11, 1926 |title= United States System of Highways Adopted for Uniform Marking by the American Association of State Highway Officials |url= https://commons.wikimedia.org/wiki/File:United_States_System_of_Highways_Adopted_for_Uniform_Marking_by_the_American_Association_of_State_Highway_Officials.jpg |scale= 1:7,000,000 |location= Washington, DC |publisher= United States Geological Survey |oclc= 32889555 |access-date= November 7, 2013 |via= Wikimedia Commons |name-list-style= amp}} US 2 replaced most of M-12 through the UP. M-45 was extended south of Sagola to the north side of Iron Mountain. Along with this change, M-69 replaced another previous section of M-12 and all of M-90. M-69 ran concurrently with M-45 between Sagola and Randville to connect these two highway segments.{{cite MDOT map |date=1926-12-01 }} By 1933, M-45 was extended concurrently along US 2/US 141 into Iron Mountain and then as an independent routing through Kingsford to the Wisconsin state line.{{cite MDOT map |date=1933-07-01 |c-link= yes |section=D4 }} Before the next year, the M-95 replaced M-45 in the UP.{{cite MDOT map |date=1934-07-01 |sections=C4–D4 }}

The current designation of M-45 dates back to 1964. M-50 was truncated to end near Lowell at I-96. The remainder of M-50 on Cascade Road, Fulton Street and Lake Michigan Drive was redesignated as M-45.{{cite MDOT map |year=1964 |link= yes |sections=K8–K9}}{{cite MDOT map |year=1965 |sections=K8–K9}} The eastern section from Business US  131 (Division Avenue) to I-96 was turned over to local control in 1972, shortening the route.{{cite MDOT map |year=1972 |link= yes |inset= Grand Rapids}}{{cite MDOT map |year=1973 |inset=Grand Rapids}} The east end would be shortened again by 1995, removing the M-45 designation east of I-196.{{cite MDOT map |year=1993 |inset= Grand Rapids}}{{cite MDOT map |year=1995 |inset= Grand Rapids}} Jurisdiction was only transferred to the City of Grand Rapids on the portion from Division Avenue west to the Grand River, leaving part of West Fulton Street under state maintenance as an unsigned trunkline.{{cite MDOT map |year=2008T |inset= Grand Rapids}} M-45 was upgraded to a four-lane divided highway in 2001–02 between Walker and the Grand Valley State campus in Allendale.{{cite news |last=Bauza |first= Margarita |title= M-45's Construction Season Approaches |work= The Grand Rapids Press |date= January 30, 2001 |page=A11}} The new alignment bypassed a section of road between 24th and 40th avenues.
