BL I-69

Interstate 69 (I-69) is a part of the

Lower Peninsula. A north–south freeway from the Indiana–Michigan border to the Lansing area, it changes direction to east–west after running concurrently with I-96. The freeway continues to Port Huron before terminating in the middle of the twin-span Blue Water Bridge while running concurrently with I-94 at the border. There are four related business loops
for I-69 in the state, connecting the freeway to adjacent cities.

Predecessors to I-69 include the first M-29, US Highway 27 (US 27), M-78 and M-21. The freeway was not included on the original Interstate Highway System planning maps in the mid-1950s, but it was added in 1958 along a shorter route. Michigan built segments of freeway for the future Interstate in the 1960s, and the state was granted additional Interstate mileage in 1968 to extend I-69 north and east to Flint. Later extensions in 1973 and 1987 resulted in the modern-day highway. The first freeway segment designated as I-69 in Michigan opened in 1967, and the last was completed in 1992, finishing Michigan's Interstate System. US 27 previously ran concurrently with I-69 from the Indiana–Michigan state line north to the Lansing area, but this designation was removed in 2002.

Route description

The entirety of I-69 is listed on the

Lake Huron Circle Tour in the Port Huron area and the I-69 Recreational Heritage Route from the Indiana state line north to the Calhoun–Eaton county line.[7] I-69 is mostly a four-lane freeway in the state of Michigan, with exceptions in the Lansing and Flint metro areas where it is six lanes and in Port Huron where it is three lanes westbound and three lanes eastbound until eastbound traffic splits into six lanes of local traffic to Port Huron and two lanes to the Blue Water Bridge
.

Northward to Lansing

I-69 in Michigan begins at the Indiana state line southeast of

business loop on the south of town. Immediately east of downtown, the freeway intersects the northern end of the business loop at an interchange that also features US 12 (Chicago Road). Farther north, the freeway turns to the northwest, crosses into Calhoun County and then over the St. Joseph River. I-69 turns back northward and bypasses Tekonsha to the town's west, intersecting M-60 in the process.[7][8]

Curving around

BL I-94 designation is overlaid on I-69; the business loop ends at the cloverleaf interchange northwest of Marshall that marks the first of I-69's two junctions with I-94 in the state . North of I-94, I-69 has one more interchange at N Drive North before crossing into Eaton County.[7][8]

In southern Eaton County, the freeway parallels the

Grand River Avenue) without any connections.[7][8]

Eastward to Port Huron

After leaving the I-96 concurrency, I-69 changes cardinal orientation and is signed as east–west from that point on. The freeway continues parallel to the Looking Glass River through suburban areas north of Capital Region International Airport. North of East Lansing, I-69 meets US 127 at a cloverleaf interchange. East of that junction, I-69 turns southeasterly passing the Hawk Hollow Golf Course and Park Lake on the way to meet the eastern end of BL I-69 just north of Lake Lansing. I-69 then turns northeasterly parallel to Lansing Road (Old M-78) to enter Shiawassee County. The freeway continues through Central Michigan farmlands, jogging north of Perry and Bancroft.[7][8]

At Durand, I-69 meets the southeastern end of M-71 on the northwest side of town. The freeway turns sharply to the northeast before turning due east near Lennon. The interchange with M-13 south of Lennon marks the Shiawassee–Genesee county line. Continuing eastward, I-69 parallels Miller Road to the north as far as the city of Swartz Creek; east of town, the two roadways cross.[7][8] I-69 parallels a line of the Canadian National Railway[9] as it enters the Flint metro area. The freeway intersects Bristol Road near the Bishop International Airport and then crosses I-75/US 23 southwest of downtown Flint. I-69, the railroad and the Swartz Creek all parallel into downtown Flint where the freeway intersects I-475 and M-54 (Dort Highway) before exiting the east side of the city.[7][8]

I-69 runs eastward out of Flint parallel to the railroad. At Davison, it intersects M-15 before crossing into Lapeer County. In this area, the freeway traverses farmlands in the southern part of the region called The Thumb. It jogs to the north around Lake Nepessing, which is southwest of Lapeer. The freeway continues through farmland to Imlay City, where it meets M-53 before crossing into western St. Clair County. I-69 continues eastward through an interchange with M-19 at Emmett.[7][8]

History

Predecessor highways

The first major overland transportation corridors in the future state of Michigan were the Indian trails.[10] None of these followed the path of the modern-day I-69 however.[11] The

Goodells, a community west of Port Huron;[17] the highway was extended to Port Huron by 1924.[18]

On November 11, 1926, the

Pittsburg, north of the modern-day I-69.[22] The section of M-78 north of Lansing was changed in 1929; the segment from Dewitt to Pittsburg was redesignated M-104, and M-78 was rerouted along a more southerly path through East Lansing to Haslett.[23][24] By 1936, M-78 was extended from Haslett all the way into Flint to end at M-21.[25] The first span of the Blue Water Bridge opened between Port Huron and Point Edward, Ontario, in 1938.[26]

Interstate Highway era

Map
1958 planning map for Michigan's Interstate Highways

The first planning maps from 1947 for what later became the

Indianapolis, Indiana, with Marshall; no connections north and east to Lansing, Flint or Port Huron were planned as part of the Interstate Highway System.[30] Around the same time, a section of M-146 near Port Huron was converted into an approach freeway for the Blue Water Bridge.[31][32]

By the middle of 1960, the first section of freeway along M-78 was opened in the Lennon area.[33] The next year, the freeway had been extended as far southwest as Durand from the end at Lennon.[34] Also in 1961, the MSHD had proposed that the section of US 27 south of Lansing be built as an electronic highway under a bid through General Motors;[35] the testing for such a roadway was ultimately done at Ohio State University instead.[36]

By the start of 1962, M-78 was a freeway from Perry at the junction with M-47 all the way to Swartz Creek near Flint.[37] On December 12, 1962, I-96 was completed around the Lansing area,[38] and M-78 was rerouted to follow it.[39] A year later, I-496 was partially opened through the Lansing area,[40] and M-78 was routed to follow it as well; the former route through downtown was redesignated Business M-78 (Bus. M-78).[41] Around the same time, I-94 was extended along the Blue Water Bridge approach freeway.[42][43]

The first freeway segment of M-21 on the east end was built from

Wadhams to Port Huron in 1966.[44][45] The next year, M-78's freeway was extended eastward to I-75/US 10/US 23 in Flint.[46][47] On October 11, 1967, the first segment of I-69/US 27 was scheduled to open between the Indiana state line and Tekonsha.[1] By the end of the year, the freeway extended north to I-94 northwest of Marshall.[46][47] The MSHD requested additional Interstate Highway mileage in 1968 under the Federal-Aid Highway Act of 1968 including an extension of I-69 from Marshall to Port Huron;[48] this extension was approved as far as I-75/US 23 in Flint on December 13, 1968.[49]

A discontinuous section of M-78 freeway east of Flint was completed in 1969.

M-56.[55][56] The M-78 designation was replaced by I-69 in 1973 after a Temporary I-69 (Temp. I-69) designation was extended northward from Charlotte through Lansing to Perry.[57][58] On September 4 of that year, I-69's designation was officially extended by Congress to end at I-475 on the east side of Flint;[49] this extension, and all subsequent ones, was of non-chargeable mileage, or segments not financed through the Interstate Highway fund.[59]

In 1980, a Flint-area politician wanted to dedicate a highway after the

BL I-69, and the remainder of that highway was turned back to local control.[62][63] The I-69 designation was officially extended once more under Congressional legislation on February 10, 1987; this last extension designated I-69 all the way to I-94 in Port Huron to reflect the 1984 openings.[49]

Another segment of freeway opened in 1987 in Clinton County between US 127 near DeWitt and Temp. I-69 near Bath.[64][65] This section was connected to the existing freeway at Perry in 1991.[66][67] The final segment of I-69 to be completed was located southwest of Lansing. It opened on October 17, 1992, when the ribbon was cut by Governor John Engler. This segment marked the last in the state to complete Michigan's portion of the Interstate Highway System.[2] At the time it was completed, I-69 was concurrent with US 27 from the state line north to the DeWitt area (exit 87) and then concurrent with US 127 to exit 89 before running alone to Port Huron.[68]

Since completion

A second span of the Blue Water Bridge between Port Huron and Point Edward opened in July 1997.[69] The St. Johns Bypass on US 27 opened on August 31, 1998;[70] US 27 was extended along I-69 about two miles (3.2 km) to the connect to the bypass, and US 127 was simultaneously removed from I-69.[71] The next year, MDOT petitioned AASHTO to decommission the US 27 designation in the state; the change was approved on April 16, 1999.[72] The state waited until 2002 to make the change.[73]

On July 23, 2001, the Michigan Legislature declared that I-69 from exit 105 in Shiawassee County east to exit 135 in Genesee County would be named the Pearl Harbor Memorial Highway.[74] In October 2001, the legislature consolidated the various legislation that created memorial highway designations in the state. Public Act 142 of 2001 extended the merged Chevrolet–Buick Freeway name to all of I-69 in Genesee County, and restored the David Dunbar Buick Freeway name to I-475.[52] The I-69 Recreational Heritage Route (now a Pure Michigan Byway) was created on October 8, 2004, to follow the freeway in Branch and Calhoun counties.[75] The Branch County segment was also dedicated as the Purple Heart Trail on July 17, 2006.[76]

In 2011, construction began to widen I-94/I-69 approaching the Blue Water Bridge,

GPS devices,[81] a problem first noted as the department was preparing to reopen the freeway in October 2012.[82] As a result, MDOT installed updated signs complete with American and Canadian flags to help prevent drivers from heading to Canada by mistake.[83]

In late 2013, construction began to reconstruct and reconfigure the I-94/I-69 interchange near Port Huron. The project will improve 3.7 miles (6.0 km) of freeway, replace several bridges and ramps and cost $76 million. In June 2014, MDOT closed the ramps from I-69 eastbound to BL I-69 through the interchange until later in the year.[84] The project was completed in September 2015.[85]
