TransAmerica Corridor I-66 and I-50

ABOUT THE CORRIDOR

The East-West TransAmerica Corridor is the solution to making America fit for 21st century transportation of goods and people from the Atlantic to the Pacific.

It will provide interstate connectivity across twelve U.S. states, connecting the only deep water port on the east coast to the ports on the west coast. Combined with I-70 and I-40, it will create a new beltway across the continent.

I-66 and I-50: A Project In Three Segments

TransAmerica Corridor I-66 and I-50

Virginia to Illinois

Utilizing the current I-66, I-79, US 119, US 460, paired with Future I-50 and Future I-73, these highways converge at Williamson, WV, until they reach Cape Girardeau, MO.

TransAmerica Corridor I-66 and I-50

Missouri to New Mexico

From Cape Girardeau, MO to Springfield, MO, with continued upgrades on US 400 to Wichita, traversing US 400 to US 50 and US 10 at Walsenburg, until reaching Farmington, NM.

TransAmerica Corridor I-66 and I-50

Arizona to California

Upgrading US 160 to US 98, spanning Page, AZ, entering Utah, and continuing past St. George, UT, and Las Vegas, NV, the corridor reaches Porterville, CA and finally San Luis Obispo, CA.

Corridor History

The TransAmerica Corridor is a multi-state effort originating in southeast Missouri and specifically Cape Girardeau. It was promoted by Congressman Bill Emerson and Congressman Hal Rogers, among others. The goal was to add a middle corridor between I-70 and I-40 that could function as a national interstate spine.

1987

The City of Cape Girardeau begins the planning process on replacing the two lane Mississippi River bridge with a new facility. The plant manager of the Cape Girardeau P&G Site started working with regional and state leaders to plan for an east-west highway (from Cape Girardeau, MO to Paducah, KY). During their local “6:30 Club” morning coffee meetings, Earl Norman, Jim Drury, Gene Rhodes, and several others begin planning for a new east-west interstate under the Regional Commerce and Growth Association group, led by Walt Wildman, who was born and raised in Wayne, County, Missouri.

1989

Some fifty individuals from across the United States flew into St. Louis to hold a conference at the Drury Inn and Suites near Lambert International Airport, solidifying the organization as the Interstate 66 Project, Inc. Dr. Lonnie Haefner, P.E. at Washington University in St. Louis is hired to prepare the Working Paper Pre-Application Proposal for a Feasibility Study of the East-West I-66 Corridor.

1990

The Interstate 66 Project, Inc. moves its headquarters from Cape Girardeau to Wichita, under the direction of Mayor Bob Knight.

1991

ISTEA declares that the National Highway System shall promote economic development; support international commerce; provide improved access to ports and airports; contribute to increased productivity; be adaptable to “intelligent vehicles,” magnetic levitation systems and other new technologies wherever feasible and economical; and help implement national goals relating to mobility.

1992

The National Interstate Highway System is formally completed.

1994

In September 1994, the Transamerica Transportation Corridor study was released to mixed findings. Most of the interstate functionality was seen as economically viable, with the other modes of transportation as not viable at the time.

1995

The Interstate 66 Project, Inc. pressed on and by 1995 the statutory route language was approved by Congress (November 28, 1995) and formally labeled as the East-West TransAmerica Corridor. The organization moves the headquarters back to Cape Girardeau, Missouri.

1996

Several state sponsored feasibility studies get underway starting in 1996: Kentucky’s “Existing Conditions” and in 1997, Virginia started its “TransAmerica Corridor Feasibility Study.”

1997

In the spring of 1997, Missouri State Senator Peter Kinder helped secure a major expansion of the Procter & Gamble Family Care manufacturing facility in Cape Girardeau, including state assistance to add a new Family Care paper production line. During the expansion discussions, Procter & Gamble’s Michael Powers, representing worldwide planning and strategy leadership, requested that Missouri examine the feasibility of the I-66 interstate corridor to strengthen long-term freight access to the region. This would allow the plant to service a much wider territory, long-term. In response, MoDOT Director Joe Mickes acknowledged the transportation need and committed to conducting an I-66 Corridor Study. Wilbur Smith & Associates releases its I-66 Corridor study for the route from Hazard, Kentucky to Williamson, West Virginia.

1998

The Virginia DOT and Michael Baker, Jr. complete the TransAmerica Corridor feasibility study looking at the route from Beckley, West Virginia to Roanoke, Virginia to Virginia Beach, Virginia.

2000

Wilbur Smith & Associates releases the feasibility study on how to construct the I-66 Corridor bypass around Somerset and London, Kentucky.

2003

The Federal Highway Administration gives its Record of Decision for the I-66 Corridor from Hazard, Kentucky to Williamson, West Virginia.

2005

By this time, Kentucky had finished its studies on the “Southern Kentucky Corridor (I-66)” with the Western Kentucky to Missouri study, which looked at many alternate routes, including the statutory route required by Congress.

2009

Somerset, Kentucky and KYTC completes and opens the I-66 and U.S. 27 interchange.

2010

The Interstate 66 Project, Inc. organization is replaced by TransAmerica Corridor, Inc. with its headquarters remaining in Cape Girardeau.

2011

Dr. Lonnie Haefner, P.E. provides an update to his “East-West I-66 Corridor Preliminary Report” in order to show the need for completion while also prepare the way for the “66 Corridor Study” and Tiered EIS funded by the DRA and USDOT.

2014

The US 460 expansion study (from Petersburg to Suffolk) was started by the Virginia DOT. In Illinois, the “66 Corridor Tier 1 EIS Study” got underway. The latter was primarily funded by the Delta Regional Authority, and required the cooperation of three state DOTs (IDOT, KYTC, and MoDOT).

2015

The “66 Corridor Tier 1 EIS Study” was cancelled in July 2015 due to Kentucky working to finish I-69, with no funding available for I-66 (TransAmerica Corridor). The Kentucky Transportation Cabinet’s Secretary also pointed out that the statutory route language prevented a bridge getting built at Wickliffe, and that the Bill Emerson Memorial Bridge must be used for the project. Kentucky’s Transportation Cabinet left the “66 Corridor Study,” causing the study to stop.

2018

The FHWA 2003 Record of Decision is rescinded for the “Appalachian Corridor” connecting I-66 from Hazard, Kentucky to I-73 at Williamson, West Virginia. This was primarily due to lack of funding for both the I-66 Corridor, along with the I-73 project’s foundation (the King Coal Highway) not having funding, nor any progress (the TAC “shares a common corridor” with I-73 in West Virginia). A new ROD will have to be issued in the future for this section in eastern Kentucky after a new Tiered EIS.

2024

Representative Hal Rogers secured $45 million in the federal Consolidated Appropriations Act of 2024 for the (I-66) Somerset Northern Bypass, signed into law on March 9th, 2024. In total, nearly $100 million is allocated to upgrade this section into I-66 and I-365 (High Priority Corridor 3 and High Priority Corridor 97). This same year, the TransAmerica Corridor, Inc. organization works with SEMO Redi, Inc. to restart the process on the I-66 project.

Now

The project is well on its way to a formal restart. The TransAmerica Corridor, Inc. Board of Directors now includes members from Missouri, Illinois, and Kentucky. The organization has garnered many letters of support from across Missouri, Illinois, and Kentucky, including municipalities, counties, chambers of commerce, economic development organizations, and elected officials. Missouri’s section for I-66 near Cape Girardeau is now on the Unfunded Needs List. IDOT is under study for a new $1 billion six lane bridge facility for I-24 at Paducah, KY, which will also hold the I-66 (TransAmerica Corridor) traffic. The King Coal Highway (divided four lane expressway) is under construction in West Virginia, and so are new divided four lane sections of the Coalfields Expressway (near Welch). The Kentucky Highway Plan (2026-2032) lists I-66 as a project again at Somerset.

Industry, Corporate, and Community Supporters

The TransAmerica Corridor alliance is a coalition-driven grassroots initiative powered by cities, counties, businesses, and official supporters working collaboratively across twelve states. United by a shared vision, TransAmerica Corridor supporters are advancing a modern Future Interstate Corridor designed to strengthen economic competitiveness, enhance national security, and expand American trade connectivity. The coalition’s greatest strength lies in coordinated multi-state advocacy, where unified regional voices amplify impact, accelerate infrastructure investment, and achieve results no single community, jurisdiction, or organization could accomplish alone.

Multi-State Support

The TransAmerica Corridor Alliance continues to build strong momentum across the heart of America, securing numerous letters of support from municipalities, counties, chambers of commerce, economic development organizations, planning agencies, and regional stakeholders throughout Missouri, Illinois, and Kentucky. These organizations represent only a portion of the growing coalition of supporters who recognize the importance of completing Congressional High Priority Corridor 3, the East-West TransAmerica Corridor.

These endorsements demonstrate increasing regional consensus around expanding economic opportunity, improving freight mobility, strengthening national connectivity, and enhancing long-term competitiveness for communities along the route. As support continues to grow, the Alliance remains committed to uniting public and private sector leaders behind one of the nation’s most significant future interstate transportation initiatives.
