Reconstruction of Kentucky 80 between Cadiz and Mayfield Progresses

Posted: 21-Feb-2004 9:41PM CST

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.

Opposition Raised Against Proposed Bridge in Breaks Interstate Park

Posted: 18-Jul-2003 6:07PM CDT
Topics: [KY 80] [Pike County]

A proposal to build a bridge near the 1,600-foot deep gorge in Breaks Interstate Park has stirred up opposition. The proposed bridge would allow access into the Kentucky side of the park; however, the bridge which would connect the park to KY 80 would be visible from overlooks over the gorge in the park. Currently all of the development in the park has been on the Virginia side because there is no road access to the Kentucky side of the park. The primary feature of the park is a 5-mile long gorge through which the Russell Fork of the Big Sandy River flows. The gorge is touted as being the deepest canyon east of the Mississippi. Residents fear that the bridge would open the park to commercialization.

Left Over Funds Being Used to Upgrade US 68/KY 80 in Christian and Trigg Counties

Posted: 8-Aug-2002 6:54AM CDT

Over $16 million in funds left over from projects that came in under budget are being used to upgrade existing portions of US 68/KY 80 near Hopkinsville. In recent years, US 68/KY 80 has been widened to four lanes; however, in some sections the existing substandard roadway was used to carry traffic in one direction. This saved money since only two new lanes needed to be constructed instead of four. Now that there is some extra money available, the old roadway will be removed and rebuild to bring all four lanes to modern standards.

US 68/KY 80 Widening 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 [Outside Link] 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.
