The Kentucky Transportation Cabinet recently presented proposed plans for widening US 68/KY 80 through the Land Between the Lakes: WPSD-TV NewsChannel 6: Kentucky: US 68 Expansion- From 2 Lanes To 4 (Dec. 5, 2005) 

A meeting to discuss the proposed widening of US 68/KY 80 through the Land Between the Lakes will be held sometime this spring: (Hopkinsville) Kentucky New Era: Road projects through LBL subject of hearing (Jan. 7, 2005) 

The U.S. Forest Service’s proposed management plan for the Land Between the Lakes proposes little change over the next 10 to 15 years: Evansville Courier-Press: Plan for managing LBL doesn't see much change (Dec. 13, 2004) 

The completion of a new lock at Kentucky Dam is not expected until 2010 or 2011. Part of the project includes the relocation of US 62/US 641 and the Paducah & Louisville Railroad to new bridges downstream from the dam. Those bridges are currently under construction: (Hopkinsville) Kentucky New Era: TVA board applauds city, county growth (Oct. 28, 2004) 

Funding to continue the reconstruction of KY 80 is included in the new Six-Year Highway Plan. The project to widen KY 80 between Cadiz and Mayfield is broken up into three phases.

• Phase 1 - Aurora to Murray - Construction on this phase of the project is nearly complete. It begins at the approach to US 68-KY 80 bridge over Kentucky Lake and continues westward to US 641 a few miles north of Murray. Construction started several years ago and should be complete this summer.
• Phase 2 - Murray to Mayfield - Construction on this phase was recently begun. This $60 million will construct a new four lane highway between US 641 north of Murray to Mayfield. Construction is expected to last for a couple of years.
• Phase 3 - Cadiz to Aurora - The Six-Year Plan includes $132 million to construct new four lane bridges over Kentucky Lake and Lake Berkeley. Construction on the bridges is scheduled to begin in 2006. Work on the widening project through the Land Between the Lakes has been delayed: the Tennessee Valley Authority gave initial approval for the project; however, ownership of the Land Between the Lakes has since been transferred to the United State Department of Agriculture forest service. Plans for the widening project are expected to be complete this summer, and construction is scheduled for completion in 2007.

The existing two-lane stretch of KY 80 between Aurora and Kentucky 58 east of Mayfield has already been renumbered as KY 402.

The US Army Corps of Engineers is in the process of building a new rail and highway bridge over the Tennessee River just below Kentucky Dam. The bridge is part of a project to build a large navigation lock at Kentucky Dam. The total cost of the project is expected to be $650,000,000. The 1200-foot bridge is expected to open in 2006; lock construction should be completed in 2012.

The bridge will carry US 62 and US 641. Both routes currently cross the river via a road on top of the dam.

I have added a new image gallery consisting of photographs I took of the roads of the Land Between the Lakes. Subjects covered include the US 68/KY 80 bridges over the two lakes, the KY 453 bridge over the Between the Rivers Canal, and road over Kentucky Lake.

Here  is some information from the Kentucky Transportation Cabinet describing the historic and environmental concerns they took into consideration while designing a new route for US 68/KY 80 through the Land Between the Lakes .

A planned project to widen US 68/KY 80 to four lanes through the Land Between Lakes National Recreation Area  is expected to cause a great deal of controversy. The $250 million project will replace the two 70-year old bridges of Lake Barkley and Kentucky Lake and construct a four lane highway on a 1000-foot right of way through LBL. The project is planned to begin in 2004, pending approval by the U.S. Forestry Service.

Proponents believe the new route would be safer than the current two lane road and increase tourism and commerce in the area; however, critics are concerned about environmental damage.
