History of I-67

I-67 was part of the original Interstate numbering plan in 1957 for a route from Kalamazoo, Michigan, to Elkhart, Indiana. A planning map shows a freeway along this routing intersecting the Indiana Toll Road just west of the State Road 19 interchange. The Michigan State Highway Department officially requested switching the I-67 designation to a route from Benton Harbor to Grand Rapids in 1958, and in the process proposed the current I-69. The I-67 designation was denied by AASHO which then assigned I-196 to the Benton Harbor to Grand Rapids route, west of the I-96 junction near Grand Rapids.

History of I-76/I-80 in Ohio

I-76 was created when I-80 was realigned in Ohio by 1962, joining the Turnpike west of Cleveland. I-80N was planned to split from I-80 near Kent and run northwest to Cleveland along OH 14. The new alignment of I-80 followed the Ohio Turnpike between the crossing west of Youngstown and OH 14. I-80 west of Youngstown became I-80S from Akron west to I-71 east of Lodi; the rest of proposed I-80 west to Norwalk (which would have crossed I-71 near was removed from the Interstate Highway System in 1971, I-80 was moved to the Turnpike between Streetsboro and southwest of Cleveland; the old route became I-480. I-76 begins at an interchange with I-71 east of Lodi, Ohio cosigned with US 224. The interstate travels east across Medina County before entering Summit County. In Akron, Interstate 76 runs concurrently with I-77 for approximately 3 miles before it becomes its own road again. I-76 continues east through the Akron suburbs and runs a rural route to just west of Youngstown, where it intersects with Interstate 80 and the Ohio Turnpike. Interstate 76 eastbound traffic exits the freeway alignment to join the Ohio Turnpike. Travelers who remain on the freeway alignment transfer to I-80 which leads through the northern Youngstown suburbs and into Pennsylvania via the Keystone Shortway. I-76 travels southeast once joining the Ohio Turnpike as it directly connects to the Pennsylvania Turnpike.

History of the I-72 Chicago to Kansas City Expressway Concept

The Chicago to Kansas City Expressway was the proposed upgrade of US 36 to I-72, a rural four-lane highway across northern Missouri and west central Illinois from Cameron, Missouri at I-35 to Springfield, Illinois at I-55. This would provide a series of rural 4-lane highways (I-35, US 36, I-72, and I-55) connecting Chicago to the North American Free Trade Agreement (NAFTA) Corridor (High Priority Corridor 23). This would reduce the amount of through traffic, primarily truck traffic, in the St. Louis, Des Moines, and Quad Cities metropolitan areas by serving as an alternate route for I-70 and I-80. The Missouri portion of this route is designated as part of High Priority Corridor 61. When US 36 is upgraded to Interstate standards across Missouri, the future western terminus of I-72 would be at Cameron, Missouri at the intersection with I-35. Currently, the west end of I-72 route is west of US 61 and flows concurrent with US 36 into Illinois. In 2004, US 36 was upgraded to a 4-lane expressway between US 61 and US 24 at the Rocket Junction. This expressway is upgraded to interstate standards August 2007.

I-67 Development Corporation Concept in Kentucky

I-67 Development Corporation was formed in 2011 to advocate running I-67 south concurrently with I-69 from Indianapolis to Washington, then extending a new terrain route to US 231 into Owensboro, Kentucky. From there, this I-67 would follow the William Natcher Parkway to I-65 in Bowling Green, Kentucky. The I-67 Develoment Corporation conducted the I-67 Corridor Feasibility Study. Neither the Kentucky Transportation Cabinet or the Indiana Department of Transportation had any interest in building a new terrain freeway through Indiana to Owensboro. The Kentucky Transportation Cabinet instead requested the Congress to establish two Interstate Corridors to Owensboro, I-369 conversion of the Audubon Parkway and the I-565 conversion of the William Natcher Parkway.

US 31 "Free-Flow" Expressway

The Indiana Senate unanimously passed a resolution in 2003 requesting the I-67 designation for US 31 between Indianapolis and South Bend. INDOT concluded that converting U.S. 31 to a "free-flow expressway" can be achieved at lower cost, in much less time, and with far less impact on existing homes and businesses while achieving the same benefits as a freeway, and has removed the concept of Interstate 67 in the state long-term transportation plans. A "free-flow" expressway removes all traffic signals and rail crossings at a fraction of the cost of upgrading the highway to interstate-freeway standards. INDOT estimated that an interstate-standard freeway would cost as much as four to five times more with little added benefit. An interstate-standard freeway would require years of federally mandated environmental review that would delay the project and needed safety improvements. A freeway would require more private property, forcing more people from their homes, require more businesses to close or relocate, and reduce the amount of property available for future development.

I-76 Extension Concept in Ohio, Indiana, Illinois {Illiana Corridor}

I-76 could be extended from I-71 in Ohio after the complete conversion of US 30 to a full freeway from I-71 to Ft Wayne. I-76 would then continue along the freeway upgrade of US 30 to Gary Indiana. From there, the proposed Illiana Corridor would become part of I-76 by modifying the original plan to avoid the Midewin National Tall Grass Praire Reserve which was a controversial issue that lead Illinois to drop its support of the Illiana highway. The new aligment would connect directly to the existing I-80 southwest of Chicago, eliminating a major drawback of the previous concept that had not connection to I-80 and terminated at I-55 making the highway a road to nowhere.




West Extension of I-76 through Ohio

I-76 is the conversion of US 30 to a freeway from I-71 to the Indiana border. Most of US 30 is already a four-lane limited access freeway, however many section will require upgrading to Interstate standards. US 30 crosses I-75 over the Norfolk Southern railroad with no direct access to I–75. The US 30 interchange with SR 696 provides the only access to both I–75. The major improvement required is to provide a full interchange between I-76 and I-75. US 30 is a four-lane divided highway to Van Wert County that will need a complete upgrade to interstate standards.




I-76 West Extension

I-76 would continue along US 30 to I-469 around Ft Wayne Indiana. I-76 runs north of the city along I-469 and I-69 with US 30 before continuing west with US 30 through Indiana up to IN 49 in Valparaiso. I-76 would then parallel IN 49 to the I-80/I-90 Indiana Toll-Road and I-94 east of Gary Indiana.




Illiana Expressway Corridor

This map shows the preferred route for the Illiana Expressway. The purpose of the Illiana Expressway was to provide a sustainable transportation solution that would improve east-west connectivity in the general vicinity of I-55 to the west and I-65 to the east. On June 2, 2015, Illinois Governor Bruce Rauner announced: “In light of the state's current fiscal crisis and a lack of sufficient capital resources, the Illiana Expressway will not move forward at this time. As a result, the Illinois Department of Transportation will remove the project from its current multi-year plan. It is the determination of IDOT that the project costs exceed currently available resources.” Indiana has only suspended its planning for the Illiana but is still advocating its construction.

In 2010, Illinois and Indiana initiated development of an Illiana Expressway under the heading of the "Illiana Corridor". The two states' transportation departments were charged with examining potential routes and proposing one through the formal federal interstate-highway planning process. In late 2012 the bi-state planning group released a draft Tier 1 environmental impact statement which was made final in January 2013. The Tier 2 process underway focused on the specific route which the planners have selected and are advocating. That route runs from I-55 west of Wilmington, Illinois to a point on I-65 east of Lowell, Indiana. This highway became very controversial both because of environmental impact and its routing only between I-55 and I-65 with no direct connection to I-80 or the I-80 Indiana Toll-Road, creating a "road to nowhere."

The I-76 Illiana Corridor

If the Illiana Corridor is directly connected to I-80, the new route would become the bypass to I-80/I-90 through Chicago. The Illiana Corridor would be the western extension of I-76 from Ohio. The other possible designation is the potential to "separate" I-80 from I-90, and use the new Illinois, Indiana, Ohio route as the "new" I-80, which is in fact how I-76 was originally proposed in Ohio. In this case I-80 would bypass Chicago, Gary, Toledo, and Cleveland, providing a less congested rural freeway for transcontinental truck traffic, reducing congestion in many of these cities. To avoid the environmental controvery, the new I-76 Illiana Expressway must run further south of the Middewin National Tall Grass Praire, and connect to I-80 west of Morris Illinois.
