Governor Stratton maintained that Illinois would continue to upgrade U.S. 50 to a four-lane limited access route in September 1960. Indiana started construction on the U.S. 50 Vincennes bypass by 1963 and four-laning of the route west from Aurora. Efforts by the northern alignment group continued unsuccessfully to the Bureau of Public Roads hearing held on July 26, 1961 and location approval of the Evansville area route.
Connecting Indiana with Kentucky, the double decked Sherman Minton Bridge (a dual suspended arch bridge) carries Interstate 64 over the Ohio River. It was completed and opened to traffic in 1961.7 The span was closed between September 9, 2011 and February 17, 2012 for emergency repair work when cracks were discovered in two supporting bridge members.
In November 2005, Tyler Allen, owner and president of USA Image Technologies in Louisville3, and J.C. Stites, founder and CEO of Autodemo LLC4 created the 86-64 grassroots organization that called for the removal of a portion of Interstate 64 adjacent to Downtown Louisville along the Ohio River. Under their plan, I-64 would be realigned onto Interstate 265 in Indiana and I-265 in Kentucky via the East End Bridge, which connected the two sections of I-265 in 2017. With this bypass in place, the remaining sections of I-64 east of I-65 and west of an area near Roy Wilkins Avenue would be renumbered as Interstate 364. A surface boulevard along the southern riverfront would allow for access through the restored waterfront area where Interstate 64 used to be. On their web page, Allen and Stites cited benefits including reduced cost of the proposed improvements to the I-64-65-71 interchange (Kennedy Interchange) and increased access to the Ohio River, making Downtown Louisville more vibrant and enhancing the regional economy.5
With upgrades at the Kennedy Interchange completed as part of the Downtown Crossing project, the idea of removing I-64 from the Ohio River waterfront is very unlikely.
The two-lane West Virginia Turnpike opened to traffic on November 8, 1954; it was later added to the mileage of Interstate 77 and a portion of I-64 (between Beckley and Charleston). The project to upgrade the turnpike from two to four lanes was completed and opened to traffic on September 2, 1987.7
Competing state interests contested over the planned route of I-64 from Interstate 81 east to Richmond. One faction favored the current route from Staunton east through Charlottesville. The second group, including Governor J. Lindsay Almond, Jr. and several members of the highway commission, advocated a southerly route from Roanoke to Lynchburg and Farmville. The route was debated for three years before the 1961 mandate by U.S. Secretary of Commerce Luther Hodges for the northern route parallel to U.S. 250.14
Spanning the waters of Hampton Roads in southeastern Virginia along Interstate 64 is the four lane Hampton Roads Bridge-Tunnel. This formerly tolled facility connects Norfolk near the Willoughby Spit community with the city of Hampton at Phoebus. The bridge-tunnel system includes a four lane viaduct over the mouth of James River and a four lane tunnel. Opened in 1957, the bridge tunnel carried only two lanes originally. Revenue bonds for the crossing were paid off by 1976 and tolls were removed. Coinciding with the toll removal was the opening of the parallel two-lane span, bringing the crossing up to its current capacity. Since this aspect of Interstate 64 was 90% covered by FHWA Interstate funds, toll collection was not extended. The U.S. 17 James River bridge to the west also saw its tolls removed in 1976 on the same day.1
One of four plans never acted upon by the Virginia Commonwealth Transportation Board (CTB) in May 1996 outlined renumbering the Hampton Roads Interstate system. One proposal realigned I-64 southward over Interstate 664 to Suffolk, where it would join its route eastward through Chesapeake to I-264 at Virginia Beach. I-64 would then overtake Virginia State Route 44 into Virginia Beach. Coinciding with this concept was establishment of Interstate 864 over former I-64 from Hampton southeast to Norfolk. SR 44 later became an extension of I-264 in August 1997.12
