Interstate 66 (west)

The U.S. Department of Transportation had plans to extend Interstate 66 westward across the country to California. However, Interstate 66 west of Wichita, Kansas, has been postponed, with the Nevada and California sections cancelled. This was because of several reasons, among them were lack of interest in the West, insufficient traffic for an interstate in the area (in fact, in some places there was no highway), and the route was to go through Death Valley National Park (to which the National Park Service was strongly opposed.) The main reason for the number 66 was to capitalize on U.S. Route 66; westward expansion of I-66 was started by businesspeople in Wichita.^{[citation needed]}

There have been some documents from Arizona as late as September 2007 that mention the possibility of I-66 in northern Arizona.

No connection is currently planned between this I-66 and the Interstate 66 in Virginia and the District of Columbia.

Route description

Kansas

I-66 was planned to extend west from I-44 near Joplin, Missouri to Wichita, Kansas. U.S. Route 400 follows the route that I-66 would have followed. Due to the construction cost and lack of facilities, plans to extend I-66 west of Wichita have been postponed.

Missouri

Missouri has had several proposals to bring I-66 through it. Currently, the two ideas for consideration are bringing I-66 from Kentucky through Illinois to Cape Girardeau (which would require going through Shawnee National Forest), or bringing the route through close to the current bridges by Wyatt to Sikeston where it could overlap the current U.S. Route 60 westward. Illinois has only recently gained interest in bringing I-66 through their state. If Cape Girardeau and Illinois cannot lure Congress to modify the route through there, Sikeston may eventually be the convergence point of three Interstates, I-55 to St. Louis and Memphis, I-57 to Chicago, and the new I-66 to Kentucky and Washington, D.C. in addition to the considerable pieces of the U.S. Highway System already present there.

On November 2, 2006, it was announced that there would be two 4-year studies funded by the Federal Highway Administration to study the impact of a Sikeston route versus a Cape Girardeau one.

Illinois

On 19 Aug 2011 officials in Cape Girardeau announced a $3.6 million grant had been secured by the Illinois Department of Transportation to study a route between Cape Girardeau on the Mississippi River and Paducah, Kentucky on the Ohio River. The route would utilize the existing Interstate 24 bridge at Paducah and new four-lane bridge at Cape Girardeau. The state will hire a consulting group to do the study. Work on it is expected to begin in 2012. Illinois last held a public hearing on the proposed corridor in 2003.

Kentucky

I-66 is planned to cross the Mississippi River east of Cape Girardeau, then continue east on a new alignment to Interstate 24 north of Paducah. It will then follow I-24 east to Eddyville, where it will turn northeast following I-69/Western Kentucky Parkway to the William H. Natcher Parkway, then turn southeast following the Natcher Parkway to I-65 near Bowling Green. Former Governor Paul Patton had I-66 written into law in Kentucky, with the routing being confirmed along the Louie B. Nunn Cumberland Parkway. That state-supported designation has been echoed at the federal level; the 2002 federal highway authorization act authorized a future Interstate between Interstate 57 in southeast Missouri and the I-73/I-74 proposed corridor in West Virginia, a few miles east of the Kentucky state line. This route is not without controversy, however; opponents note that the segment between London and Somerset, currently served by the two- to four-lane Kentucky Route 80, would risk damaging delicate karst formations and environmentally sensitive areas of the Daniel Boone National Forest. Going between London and Hazard, Interstate 66 would parallel or replace the Super two Hal Rogers Parkway. The Interstate would then turn northeast toward Pikeville, KY and east to West Virginia.

Construction was completed in 2011 on a less controversial segment in western Pulaski County, relocating the eastern terminus of the Louie B. Nunn Cumberland Parkway to US 27.

Numbering considerations

A completed I-66 would not be in strict compliance with AASHTO Interstate Highway System numbering standards,^{[citation needed]} since most of it would actually run south of existing I-64. A similar condition exists where I-75 and I-85 cross over at Atlanta, Georgia, so it is not without precedent. I-99 in Pennsylvania is also out of sequence, though its designation was written into law by its Congressional sponsor, Bud Shuster, not designated by AASHTO. However, I-64 doesn't yet exist west of St. Louis Metro, so west of around Poplar Bluff, this section of I-66 would comply with AASHTO, since the western terminus of I-64 is at this longitude.

Another concern is that the proposed route of I-66 in Missouri and Kansas would cross the former path of historic U.S. Route 66. However, as the US route has been decommissioned, there would be no official route numbering conflicts. Proposed expansions of other Interstate corridors are expected to have intersections with similarly numbered active US routes, such as the future intersection of Interstate 69 and U.S. Route 69 in Texas, and Interstate 74 and US 74 in North Carolina.
