Interstate 64


Interstate 64 connects the St. Louis metropolitan area east to the Hampton Roads area of southeast Virginia. Along the way, I-64 connects with Mount Vernon, Illinois; Evansville, Indiana (via former Interstate 164/new I-69); Louisville, Kentucky; Charleston, West Virginia; and Richmond, Virginia.

Interstate 64 doubles as the southernmost extend of the Avenue of the Saints corridor between Wentzville and Lindbergh Boulevard (U.S. 61) at Ladue. Although much of the Avenue of the Saints corridor north of I-64 and I-70 consists of four-lane divided highway or expressway, it is not an Interstate route. The corridor extends north from the St. Louis area to Hannibal, Iowa City, Iowa and ultimately St. Paul, Minnesota.

In the Norfolk-Hampton Roads area, Interstate 64 forms half of the Tidewater belt system, which results in I-64 curving south then westward, giving the eastbound direction a western orientation. The furthest east point along the route is located near its eastern interchange with Interstate 264 in Virginia Beach. One of four plans never acted upon by the Virginia Commonwealth Transportation Board (CTB) in May 1996 outlined a renumbering of the Hampton Roads Interstate system, with one proposal realigning I-64 to replace I-664 southward to Suffolk before joining its route eastward through Chesapeake to overtake Virginia 44 into Virginia Beach. Coinciding with this idea was the renumbering of the former I-64 southeast from Hampton to Norfolk as I-864. VA 44 later became an extension of I-264 in August 1997.12

Together the easternmost 35 miles of Interstate 64 and all 20 miles of Interstate 664 constitute the Hampton Roads Beltway. A distinct trailblazer is used for the Beltway, with directional placards indicating inner or outer depending upon the direction traveled. Furthermore the portion of I-64 between I-264 and 664 at Suffolk and I-264 at Virginia Beach does not use cardinal directions due to the orientation of the freeway.

Parallel/Historic U.S. Routes

Interstate 64 and U.S. 40 & 61 are merged from the western terminus at Wentzville through to Ladue, where U.S. 61 turns south along Lindbergh Boulevard. I-64 and U.S. 40 remain cosigned through to St. Louis and the Poplar Street Bridge across the Mississippi River. I-64 and U.S. 40 part ways at the East St. Louis Interchange, with U.S. 40 taking I-55 and I-70. East of St. Louis, Interstate 64 replaced former U.S. 460, which used to follow portions of Illinois 15, 142, and 14 and Indiana 66 and 62 en route to Louisville, Kentucky. The route also overlaps with U.S. 50 from Caseyville to O'Fallon, Missouri.

Once at Louisville, Interstate 64 parallels U.S. 60 more or less east to Virginia. Exceptions to this include the toll section where Interstate 64 is combined with Interstate 77 (West Virginia Turnpike) and between Staunton and Richmond, where it parallels U.S. 250.

Planned Improvements

In Louisville, Kentucky, major improvements and upgrades are underway for the interchange between Interstates 64, 65 and 71 at the "Spaghetti Junction" (Kennedy Interchange) as part of the larger Ohio River Bridge Project. While this project primarily focuses on the construction of a new Interstate 265 bridge ("East End Bridge") and doubling capacity of the Interstate 65 Downtown Crossing by building a parallel span for northbound traffic, the improvements planned for the Kennedy Interchange are significant. Improvements cited from the project web page include:6

  • Increased capacity for the ramp system
  • A new interchange design at Mellwood Avenue and Interstate 64
  • A new partial interchange at Interstate 71 and Frankfort Avenue/Ohio Street
  • Realignment of Interstate 64 between Interstate 65 and Interstate 71 to a new alignment south of the existing alignment
  • Extension of Witherspoon Street one mile to Frankfort Avenue/Ohio Street

In December 2006, costs were estimated for the improvements slated for Interstate 64, Interstate 65, and Interstate 265 in Louisville. Reaching over 60% of initial estimates, the cost for two new Ohio River Bridges and the reconstruction of the Downtown "Spaghetti Junction" interchange between Interstates 64, 65 and 71 was estimated to be $3.9 billion. The components of this major construction initiative were as follows in 2006:8

  • Interstate 265 Connector/East End Bridge — Cost: $1.29 billion; Estimated Completion: 2013.
  • Interstate 65 Downtown Louisville Bridge Replacement — Cost: $868.4 million; Estimated Completion: 2019.
  • Interstate 64, 65, and 71: Reconstruct the Kennedy Interchange — Cost: $1.74 billion; Estimated Completion: 2024.

Funding was a major concern, and lack of funding adjusted the construction phase. Work finally started on the Kennedy Interchange project on July 15, 2013. Construction runs through the end of 2016.9


The original western terminus was in Illinois at the East St. Louis interchange with Interstates 55 and 70. Interstate 64 was extended westward in 1993 from East St. Louis through St. Louis to Intestate 270 at Town and Country, Missouri via the Daniel Boone Expressway (U.S. 40). Further extension west into St. Charles County followed through a series of upgrades to the Daniel Boone Expressway (U.S. 40 & 61) to Interstate standards.

The west end of I-64 was located at the approach to the U.S. 40-61 bridge over the Missouri River until 2003. Upgrades continued westward to the Missouri 94 interchange, and then Highway K in 2004.2 The last section, which opened during a ceremony held at the new interchange at Prospect Road on October 14, 2009, extended Interstate 64 northwest to Interstate 70 in Wentzville.

Interstate 64 underwent major improvements in the St. Louis area between 2000 and 2009 as part of the "The New I-64" construction project by MoDOT. I-64 between Ballas Road and Interstate 170 was closed for reconstruction between January 2, 2008 and December 31, 2008. The stretch east from I-170 to Kingshighway Boulevard faced a similar closure on December 15, 2008, as the western section reopened. The entire project was completed on December 7, 2009. The project redesigned the 1950s-built freeway to modern standards, with new overpasses, redesigned interchanges and a high-speed connection with I-170 in addition to landscaping and architectural improvements.

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 a web page 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 Interstate 265 in Kentucky via the East End Bridge, which will connect the two sections of I-265 in 2016. 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 Interstate 64-65-71 interchange (Kennedy Interchange) and increased access to the Ohio River, making downtown Louisville more vibrant and enhancing the regional economy.5 For more, visit Allen and Stites'

With upgrades at the Kennedy Interchange underway until 2016 as part of the Downtown Crossing project, the idea of removing I-64 from the Ohio River waterfront is unlikely to happen.

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 Interstate 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

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 thus tolls 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

Historic Western Terminus - Missouri K - O'Fallon, Missouri
The western terminus of Interstate 64 used to be at Exit 10, Junction Missouri 94. It was extended west by one mile, to Exit 9, Junction Missouri K. WB I-64 crosses the Missouri River along the old span of the Daniel Boone Bridge. The bridge currently handles three narrow lanes of traffic. After winding through the bottoms of Weldon Spring and passing the Missouri Research Park, I-64 adds a fourth lane to accommodate traffic exiting onto Route 94. Photo taken by Brian Dowd (01/31/04).
Westbound Interstate 64 reaches Exit 10, Junction Missouri 94. At the busy Missouri 94 interchange, traffic exiting to St. Charles utilizes the right lane of the bridge, while Westbound traffic heading toward Defiance and ultimately toward Augusta and the Missouri Wineries will utilize the left lane. Toward the east, Missouri 94 goes through Weldon Spring and St. Peters on its way to connecting to the Missouri 364 freeway, which opened in December 2003 with ten lanes across the Missouri River to accommodate intercounty traffic. Photo taken by Brian Dowd (01/31/04).
Westbound Interstate 64 reaches Exit 9, Junction Missouri K. This is the slip ramp from westbound to the collector distributor roadway between Missouri 94 and Missouri K. Photo taken by Brian Dowd (01/31/04).

Interstate 64 nudges westward to the interchange with Missouri K just west of Missouri 94. Pictured here is the Interstate 64 westbound on-ramp from Missouri K northbound in St. Charles County. The interchange between the two highways opened in early 2004. Photo taken by Jason Oesterreicher (06/18/04).
Past the Missouri K entrance ramp to westbound Interstate 64, a sign panel alerting drivers to the end of Interstate 64 was placed. This sign in the typical MoDOT style announces not only the end of the designation bu also the designation of the road that continues. In this case, the expressway continued northwestward as U.S. 40/61. Photo taken by Brian Dowd (01/31/04).

Eastern Kentucky - 1970 Kentucky Official Highway Map.
A short segment of I-64 was incomplete by 1970. This stretch ran east from Grayson to U.S. 60 in western Boyd County. The interstate was finished across the Bluegrass State in 1976.10
Southern West Virginia - 1968.
Interstate 64 was initially completed east of Beckley, West Virginia in the White Sulphur Springs vicinity. The route was finished in West Virginia by 1988.
Hampton Roads, Virginia - 1969. This map shows a slightly different alignment then was ultimately built for I-64 across Willoughby Bay.
Interstate 64 utilized a portion of Virginia 168 as part of the through route southward from the Hampton Roads Bridge-Tunnel until 1976, when the route was completed through Norfolk.11
