Interstate 275 Michigan
Overview
Interstate 275 forms a western bypass of Detroit from north of Monroe to Romulus, Detroit Metropolitan Wayne County Airport (DET), Canton and Livonia. The freeway was originally planned to reconnect with Interstate 75, following a path just west of West Bloomfield and Waterford. It was not completed as U.S. 23 already provided a long distance bypass between Toledo, Ohio and Flint.
I-275 traverses mostly rural areas of northeastern Monroe County to the east of Carleton into semi-rural areas of western Wayne County. The freeway leads north to Eureka Road (Exit 15), which provides access to Detroit Metropolitan Wayne County Airport (DET) for travelers originating from Monroe and Toledo to the south. The route shifts westward from the airport perimeter to cross paths with Interstate 94 in Romulus.
The remainder of Interstate 275 north parallels Haggerty Road as a commuter route along a mixture of industrial areas, apartment complexes and business parks. A large directional cloverleaf interchange at Livonia brings Interstate 96 north onto I-275 west from the Jeffries Freeway opposite the M-14 freeway west to Ann Arbor. The two routes share approximately 5.7 miles of pavement north along a commercialized corridor to Farmington Hills and Novi. I-275 ends at a large interchange complex where I-96 resumes a westward heading to Lansing, I-696 ties in from Southfield to the east and M-5 intertwines from Farmington to Novi.
History
The mileage for Interstate 275 was not included in the initial 1,080-mile Interstate system proposed by the state of Michigan in 1954. Area growth in the Detroit suburbs however made the route a necessity. Construction for the entire 58-mile route of Interstate 275 was estimated to cost $95 million and planned to start in segments between January 1970 and July 1971. The Monroe County portion was scheduled for bidding between February and June 1971.1
As originally envisioned, Interstate 275 was to lead north from I-75 at Newport to Detroit Metropolitan Airport and Romulus where it would swing west for about three miles then continue north to Plymouth and Northville to meet I-75 again midway between Detroit and Flint. 14 interchanges were proposed on the 30-mile freeway between I-75 and Interstate 96 in Oakland County.1
Construction along Interstate 275 ran through 1977. The final 26-mile section ran north from U.S. 24, north of Monroe, to M-153 (Ford Road) in Wayne County. The $250-million project was completed on January 13, 1977 with six overall lanes. The last section built tied into a three-mile stretch between I-75 and U.S. 24 and the 11-mile section north to I-696 at Novi that both opened in 1976.2
The remaining 24-mile segment of proposed Interstate 275 leading north from I-696 to I-75 northwest of Pontiac was canceled in 1977. Protests from Oakland County residents cited that the route was not necessary and that it would take away from needed agricultural and recreational land. The projected path also took I-275 through a 200-acre wetland that was home to the southernmost stand of black spruce in North America. Planners subsequently shifted attention to the upgrading of U.S. 233

A four mile section of Interstate 275 opened to traffic in 1975 from M-153 (Ford Road) to temporary ramps at Schoolcraft Avenue near Plymouth and Livonia.4
Very few maps showed the unconstructed section of I-275 leading north from I-96 and 696 at Novi back to Interstate 75. A five mile stretch of this route was eventually built as the Haggerty Connector (M-5).

Exit 1 veers away from Interstate 696, as the freeway defaults onto I-96 west in 1.75 miles. A long ramp turns southward to pass over M-5 and merge onto the left-hand side of I-96 east and the southbound beginning of I-275 as the pair head south to Livonia. Photo taken by Scott Steeves (11/05/06). |

The first sign for the interchange complex with Interstate 275 south, I-696 east and M-5 north appears one mile ahead of Novi Road on Interstate 96 east. Photo taken 11/06/11. |

Exit 162 departs I-96 east for Novi Road as a diagrammatic overhead outlines the forthcoming movements of the back to back wye interchange with I-696 (W.P. Reuther Freeway) east and trumpet interchange with M-5 north. Photo taken 11/06/11. |

The left three lanes default onto Interstate 696 east, which connects I-96 with M-5 (Grand River Avenue) southeast to Detroit and I-94 east to Port Huron. The right two lanes carry I-96 east along side Interstate 275 south through Farmington Hills and Livonia. Photo taken 11/06/11. |

Meadowbrook Road spans Interstate 96 east at the split with I-696. Interstate 696 quickly splits thereafter with M-5 (Grand River Avenue) south. M-5 east from I-696 is the historical alignment of Interstate 96. Photo taken 11/06/11. |

The first in a series of diagrammatic signs for the interchange complex with Interstate 696 (Walter P. Reuther Freeway) and M-5 was posted at the off-ramp (Exit 167) to Eight Mile Road on I-96 west & 275 north. Separate panels for the I-96 pull through and I-696 and M-5 (Grand River Avenue) were installed here by 2011. Photo taken 11/07/09. |
 |
Nearing the Nine Mile Road underpass, Interstates 96 & 275 partition in one mile into separate roadways. I-96 branches to the west along a sweeping ramp to Novi and Lansing with Exit 165 forming a collector distributor roadway to M-5 and I-696 east. Photo taken 11/07/09. |
 |
Separate panels were installed on this sign bridge by 2011, showing a single lane for M-5 north and two lanes for I-696 east to Port Huron (via I-94 east) and M-5 south to Grand River Avenue. Photo taken 11/07/09. |

Traffic partitions at Exit 165 as Interstate 275 north concludes. Three ramps depart in succession from the c/d roadway, with the first departing for the M-5 freeway east to the city of Farmington. M-5 north from I-696 travels initially as a freeway, then as an at-grade expressway to Pontiac Trail. Photo taken 11/07/09. |

M-5 south partitions with a two-lane c/d roadway at 12 Mile Road. The pull through panel referenced the upcoming trumpet interchange with Interstate 96 and 275. Interests to I-96 west for Lansing must use the c/d roadway as the remainder of M-5 south turns east at I-696. Photo taken by Frank Gillon, Jr. (05/20/07). |

M-5 south becomes M-5 east as it transitions to the freeway spurring east from Interstate 696 to Farmington Hills. Just beyond the bridges across the Walter P. Reuther Freeway is the slip ramp onto adjacent Interstate 96 east & 275 south. Photo taken by Frank Gillon, Jr. (05/20/07). |

Interstate 96 turns south from Novi to Livonia as it travels along side Interstate 275 to the M-14 freeway. I-275 provides a bypass of Detroit for the 60-mile drive to Toledo, Ohio. Motorists remaining along M-5 east next meet a loop ramp for Interstate 696 east to Smithfield, Warren and St. Clair Shores. Photo taken by Frank Gillon, Jr. (05/20/07). |
