Doing the 'Double Cross Over Diamond'

Aug 19, 2011

An innovative highway interchange in Lexington remains a ‘work in progress.’  Work on the ‘Double-Cross-Over-Diamond’ interchange at Harrodsburg and New Circle is backing-up traffic, especially during  peak driving times.  Opening a third lane in each direction will help, but, Site engineer Tony McGaha can’t say when that will happen.

“At this time we don’t have a real firm date.  Like any construction project, there are way too many variables to really give you a date.  As soon as we feel that third lane is safe for the public and we’ve got the work completed so the workers are protected, we will open it with no delay on it,” said McGaha

Still, McGaha expects the third lane to open within a few weeks.  State Transportation officials say the double cross diamond project is probably about 60 percent complete.

Lexington’s innovative ‘Double-Cross-Over-Diamond’ interchange has been a busy place this past week.  .  Steve Cummins, who’s with Lexington’s Traffic Management Center, adds they’re tweaking traffic lights to improve flow.

“And we are currently now running ten very unique timing plans through this area to help reduce the congestion levels. And this is something that is very good partnership level between the state and the city that we’re able to take advantage of our abilities and help reduce those congestion levels,” explained Cummins.

The innovative ‘Double-Cross-Over-Diamond’ interchange under construction on Lexington’s south side may become a road map of sorts for other Kentucky communities.  While, the project is just over half complete, Robert Nunley with the state transportation department, says the cross over diamond may soon be copied by other Kentucky communities.

“If it performs as we’re anticipating that it will, based on the models,  then we would probably consider it at other locations throughout the state for that matter, not just within the city of Lexington,” said Nunley.

The ‘Double-Cross-Over-Diamond’ interchange is only found in a handful of communities across the U-S. It’s designed to improve traffic flow and reduce accidents by eliminating left turns.
