Interstate 64 (I-64) in the US state of Kentucky travels for 191 miles (307 km), passing by the major towns and cities of Louisville, Frankfort, Lexington, and Ashland. It has several major junctions with other Interstates, including I-65, I-71, I-264, and I-265 in Louisville and I-75 in Lexington.

The portion of I-64 in Kentucky is host to two "exceptionally significant" structures indicated by the Federal Highway Administration (FHWA). One is the Cochran Hill Tunnel,^[2] a twin tube at Cherokee Park in Louisville built in 1974,^[2] and the other is a 1960s-era modern-styled rest area near Winchester.^[3]

In Downtown Louisville, I-64 passes under a public plaza called the Riverfront Plaza/Belvedere, one of the only structures in the state built on top of an Interstate.

Between the Indiana state line and Lexington, I-64 is named the Daniel Boone Expressway.

The entire length of I-64 in Kentucky has been designated as a portion of the Purple Heart Trail.^[4][5]

Route description

I-64 enters Kentucky at Louisville, paralleling the Ohio River along the Riverfront Expressway. It intersects with several downtown interchanges before coming to the Kennedy Interchange, where it intersects I-65 and I-71 in a tangle of ramps often referred to as the "Spaghetti Junction". Moving eastward, I-64 passes through Shelbyville, Frankfort, Midway, Lexington, Winchester, Mount Sterling, Owingsville, and Morehead, before leaving the state near Ashland at Catlettsburg. It overlaps I-75 as it makes an arc around the northeast of Lexington's urban core, with the exit numbers for I-75 used for the concurrent portion. The two Interstates separate a few miles east of downtown Lexington.

History

The Cochran Hill Tunnel in Louisville, also known as the Cherokee Park Tunnel, underwent restoration in 2001, which involved the reconstruction of the concrete pavement, the installation of new tiles, and the improvement of lighting. Later, the lights in the tunnel were replaced after multiple lights were found to be faulty. The tunnels, which opened in 1974, are one of three sites in Kentucky deemed "exceptionally significant" by the FHWA. The designation meant that it will be very difficult for the stretch of Interstate running through Cherokee Park ever to be widened.^[3]

Construction began on a Kentucky Route 180 (KY 180) interchange improvement project in the summer of 2006.^[6][7] The $34-million (equivalent to $45.6 million in 2022^[8]) project entailed the rebuilding of six bridges, the widening of KY 180 to four lanes in the vicinity of the interchange, and the conversion of the ramps into a diamond interchange. The project was finished in the autumn of 2008.

In March 2007, Governor Ernie Fletcher signed Senate Bill 83, which allowed for an increase in speed limits on rural Interstates and parkways. Speed limits on rural sections of I-64 were increased from 65 to 70 mph (105 to 113 km/h), following an engineering study by the Kentucky Transportation Cabinet. New signage was installed in July^[9]

On June 7, 2007, I-64 between the junction of I-264 and I-65 and I-71 in Downtown Louisville was closed to through traffic.^[10] The section of highway featured three lanes of traffic in each direction on an elevated viaduct paralleling the Ohio River, carrying 90,000 vehicles per day. The closure was part of a $50-million (equivalent to $68.3 million in 2022^[8]) refurbishment project that involved replacing 132 expansion joints and repaving more than four miles (6.4 km) of Interstate and interchanges.^[11] The work was completed in two phases, starting with the entire project area being closed on three weekends in June, followed by a section of highway closed from 3rd to 22nd streets in early July to early August. However, the Interstate was not finished because of the section between Frankfort and Lexington. The state could not attain the right-of-way here because of very famous horse parks northwest of Lexington. After a couple of tries to get the right-of-way, the state was able to get the right-of-way and began construction on this segment. It was the last segment of I-64 to be completed in Kentucky.
