Federal legislation

On May 2, 2008, the United States House of Representatives passed HR-1195 (SAFETEA-LU Technical Corrections Act of 2008) which designates the Pennyrile Parkway from Henderson to Nortonville and the Western Kentucky Parkway from Nortonville to I-24 at Eddyville as Future I-69. It further designates the Audubon Parkway as a future spur (I-X69) of I-69 once necessary upgrades are completed. Then-President George W. Bush signed the bill on June 6, 2008, and Future I-69 signs began appearing on the parkways in the middle of 2008.^[3][4][5][6] This legislation applied the Future I-69 designation to the following roadways:

• Pennyrile Parkway from just south of the Audubon Parkway in Henderson to the Western Kentucky Parkway in Nortonville (future I-569)
• Western Kentucky Parkway from the Pennyrile Parkway to I-24 in Eddyville
• I-24 from Eddyville to the Purchase Parkway in Calvert City
• Purchase Parkway from I-24 to the US 51 interchange at the Tennessee state line

I-69 concurrent with Western Kentucky Parkway near Dawson Springs during transition period; now only I-69

All four highways, except for the section of the Purchase Parkway south of Mayfield, are now signed as I-69.^[7] Signage and milemarker posts were changed in mid-December 2012.^[8]

SIU 5

A 2007 engineering study for SIU 5 identified then-current conditions along the Pennyrile and Western Kentucky parkways. The report identified seven overpasses that fell short of the 16-foot (4.9 m) minimum vertical clearance necessary for Interstate Highways. An additional 28 mainline bridges were identified for not meeting the minimum horizontal clearance of 38 feet (12 m). Most—if not all—of the aforementioned bridges were built during construction of the parkways in the 1960s and are nearing the end of their serviceable lifespans and due to be replaced. The main issues concerning the 16 interchanges in SIU 5 were short acceleration/deceleration lanes (the average is 615 feet (187 m) while Interstate standards mandate 1,200 feet (370 m)) and tight curve radiuses at interchanges with loop ramps.^[9] A particular challenge was reconfiguring the cloverleaf interchange between the Pennyrile and Western Kentucky parkways in Nortonville to accommodate the future movement of traffic primarily between points north and points west.

According to the Kentucky Transportation Cabinet (KYTC) 2006 Six-Year Transportation Plan Executive Summary, the KYTC "recently completed a study of the parkway upgrade needs from Interstate 24 to Henderson" (SIU 5). The summary further stated that "Continuing work on Interstate 69 in Kentucky will depend upon the financial support that can be garnered for the project through federal reauthorization and appropriations processes". The Transportation Plan estimated that the cost of upgrading the parkways would be about $700 million.

Nonetheless, the required improvements may be performed on individual segments of the parkways when the existing road surfaces reach the end of their lifespans, in what are known as "Pavement Preservation Projects". During a pavement preservation project, the existing pavement is removed, repairs are made to the highway's sub-base, and the road is then resurfaced. During such a project, bridges and overpasses may be rehabilitated or replaced, drainage systems are upgraded, and other modifications are made to improve safety on the road without completely reconstructing it, allowing it to remain at least partially open during construction.

Two projects on the Pennyrile Parkway and the Western Kentucky Parkway in Hopkins County were evidence that Kentucky took this approach. In 2007, work began on a $14.9-million (equivalent to $20.4 million in 2022^[10]) project to replace seven miles (11 km) of pavement on the Pennyrile Parkway segment slated for the I-69 designation. A similar $23-million project (equivalent to $33.3 million in 2022^[10]) in 2005 replaced and upgraded 11 miles (18 km) of pavement on the Western Kentucky Parkway west of the interchange with the Pennyrile Parkway, which was also slated to become part of I-69.

Several public meetings were held in towns along the parkways in late November and early December 2007 where Kentucky officials provided detailed information on upgrading the parkways, including changes to the projected cost for the upgrades. The adjusted cost of upgrading the parkways in SIUs 5 and 6 was pegged at around $300 million, significantly lower than initial estimates of $700 million. Of that $300-million pricetag, high-priority projects accounted for about half ($145 million) of the total cost. Kentucky transportation officials also raised the idea of applying for a waiver that would allow the parkways to immediately be signed as I-69, making the parkways eligible for federal Interstate Highway funds to complete the upgrades. Without the I-69 designation, the parkway sections slated to become I-69 would not be eligible for Interstate Highway funds for upgrades.^[11] Kentucky officials announced that no funding for I-69 was included in the 2008–2014 Transportation Improvement Plan.^[12]

In January 2010, then Governor Steve Beshear released the next draft Six-Year Plan for consideration by the Kentucky General Assembly. The proposed plan included the reconstruction of several interchanges on the Pennyrile and Western Kentucky parkways. The proposed work would upgrade the interchanges to Interstate standards as required to get the parkways signed as I-69. Pending approval and funding, the interchange work would begin in 2012 and be finished by 2015.

In 2014, work began on the required upgrades to the Pennyrile Parkway in anticipation of the I-69 designation. The cloverleaf interchange with I-69/Western Kentucky Parkway was modified to allow highspeed movements between points north and points west. During the same time frame, several interchanges along the Pennyrile were also reconstructed, and cable barriers were installed in the median. In April 2015, the KYTC awarded a $3-million contract (equivalent to $3.64 million in 2022^[10]) to install I-69 and US 41 signs on the Pennyrile Parkway. The work was completed on November 16, 2015.

SIU 6

From Eddyville, I-69 follows I-24 for 17 miles (27 km), then turns southwest on the Purchase Parkway. I-69's designation along the Purchase Parkway from I-24 to the Tennessee state line at South Fulton, Tennessee, was written into law with the fiscal year 2002 Transportation Appropriations Bill.^[13] However, many of the same issues that are being addressed in SIU 5 arise in SIU 6 as well, and the Commonwealth of Kentucky is upgrading the Purchase Parkway in a similar fashion. The massive interchange with US 45 and US 51 at the Tennessee state line in South Fulton is the main challenge for completing SIU 6 and has been broken out as a separate project from SIUs 6 and 7.

Kentucky is the only state that will be routing nearly its entire portion of I-69 over existing freeways, allowing the state to avoid years of costly environmental studies, and thereby enabling the KYTC to upgrade the parkways to I-69 as soon as funding becomes available. Technically, the Commonwealth of Kentucky could request a waiver from the American Association of State Highway and Transportation Officials (AASHTO) that would allow the state to apply the I-69 designation to its parkways before upgrades are completed, but this would only be able to have been done if adjoining segments in Tennessee or Indiana are completed first.

The Purchase Parkway has been designated as future I-69, but the route could not be signed as I-69 until several interchanges, including the interchange with I-24, are upgraded to Interstate standards. The northern portion of the parkway between Mayfield and I-24, including the reconfiguration of the KY 348 interchange at Benton from a toll-booth design (with opposing loop ramps) to a diamond interchange, the installation of cable barriers in the narrow parkway median, and resurfacing of the mainline to increase bridge clearances and lengthen merge lanes at other interchanges along this section was part of the upgrade to I-69. A $37-million contract (equivalent to $44.9 million in 2022^[10]) to reconstruct the I-24/Purchase Parkway interchange was awarded to Jim Smith Contracting Company on November 20, 2015. Construction on the I-24/Purchase Parkway interchange began in early 2016,^[14] with the project completed in July 2018. A similar contract to reconstruct the parkway interchanges at the south end of the Mayfield Bypass (exit 21) and KY 80 was let in February 2016. The section of the Purchase Parkway north of Mayfield received I-69 signage in July 2018.^[15] A contract for the conversion of the last remaining tollbooth-style interchange requiring reconfiguration, located at KY 339 in Wingo (exit 14), was awarded again awarded to Jim Smith Contracting Company in December 2022 at a cost of $33.9 million. The project will turn this exit into a diamond interchange with extended ramps to meet interstate standards. The current ramps are expected to be closed for up to 90 days between July 10 – October 10, 2023 as the construction project begins.^[16] Improvements to the exits 1 (US 51) and 2 (KY 307) will also be made.^[17][18] The project is scheduled for completion on December 15, 2024.^[19] After construction, I-69 will be extended down south to Fulton and the Tennessee state line.^[20]

SIU 7

The interchange between the Purchase Parkway, US 45, and US 51 straddles the Tennessee state line between the cities of Fulton, Kentucky, and South Fulton, Tennessee. Officially part of SIU 7, the interchange was broken out from the environmental impact statement (EIS) prepared by the Tennessee Department of Transportation (TDOT) for SIU 7 at a time when Tennessee was moving forward with planning for the remainder of SIU 7 (all of which, except for a 1.5-mile (2.4 km) section of the Purchase Parkway approaching the Fulton–South Fulton interchange, lies within Tennessee). It was agreed upon by the Federal Highway Administration (FHWA), the KYTC, and TDOT to prepare a separate environmental assessment (EA)/EIS for the Fulton–South Fulton interchange when both states were ready to perform its reconfiguration to accommodate I-69. As Tennessee continues to make progress toward completing the unbuilt portion of SIU 7 to the south and Kentucky's upgrades to the Purchase Parkway from the north, both states indicated their intention to start work on reconfiguring the Fulton–South Fulton interchange. A joint EA/EIS will be prepared by the KYTC and TDOT and submitted to the FHWA for a record of decision (ROD) prior to right-of-way acquisition and construction. The 2016 Kentucky Six Year Road Plan includes $7.8 million in fiscal years 2019 through 2022 to complete environmental studies, ROW acquisition, and utility relocation in anticipation of reconstructing the interchange thereafter.

SIU 4

SIU 4 is still in the planning stages, but Kentucky and Indiana had planned to finance a new bridge across the Ohio River with tolls.^[21] The preferred alternative for SIU 4 was to leave the Pennyrile Parkway near its north end and cross the Ohio River to the former I-164 near Evansville, Indiana, and then use the former I-164 to I-64. All of I-164 was redesignated as I-69 in 2014,^[22] but the Ohio River bridge plan had stalled in the late 2000s and early 2010s, due to lack of funding from both states.^[23] However, with the completion of SIU 5 in Kentucky and with I-69 connected to Indianapolis via Indiana State Road 37 in Indiana, both states made completing the Ohio River Bridge a top priority.

On June 30, 2016, then-Indiana Governor Mike Pence and then-Kentucky Governor Matt Bevin announced an agreement to resume environmental studies and developed a funding strategy to complete the Ohio River Bridge and its approaches. Indiana contributed $17 million to restart and led the environmental studies that culminated in an approved EIS and ROD that allowed construction to begin. Environmental studies have taken three years to complete, with right-of-way acquisition and construction expected beginning thereafter. Parsons Transportation Group, a California-based firm with offices in Indiana, was picked to complete environmental and preliminary design work on November 15, 2016. Kentucky has committed over $43 million in its 2016 Six-Year Highway Plan for design and right-of-way acquisition for the bridge.^[24][25]

Kentucky Governor Andy Beshear has proposed $267 million in his first Six-Year Highway Plan for the I-69 bridge. Of that, $77 million would become available from 2020 to 2022 and the rest from 2023 to 2026. The proposed money source developed the project and then began a portion of construction running from KY 425/Henderson Bypass to US 60. Due to the financial situation regarding the current COVID-19 pandemic, only $37 million was approved due to possible budget deficits.

On September 16, 2021, a combined final EIS and ROD was issued. On December 21, 2021, the first of two contracts for the bridge was awarded (running from the I-69/KY 425 interchange to US 60, more than six miles (9.7 km) in total length). It went to the design–build bid of Ragle Inc. and Stantec Consulting Services, Inc. for $158 million. Groundbreaking took place on June 23, 2022, and construction of the first phase is scheduled to complete in late 2025 at a cost of $257 million.^[26] Construction for phase 2 will begin 2027. It will extend I-69 from US 60 to Evansville, Indiana which includes a new Ohio River crossing bridge. It is expected to be completed in 2031 in which I-69 will connect Indiana to Kentucky.^{[27][28][29][30]}
