So… What’s a double crossover diamond?
In a double crossover diamond interchange traffic through an interchange follows clearly defined curbs, signs, pavement markings and state-of-the-art signals to move briefly over to the left side of the road. This eliminates left turns against oncoming traffic. Motorists who need to continue through the interchange then cross back to the right side of the road, leading to the “double crossover” name.
“We expect the improvements at the I-71/75 and Richwood Road interchange to improve safety, reduce travel time delays, and provide better connections to local destinations and a growing number of businesses in the area,” said Bob Yeager, Chief District Engineer for KYTC’s District 6 Office. “We also realize that it may take some time for drivers to adjust to the new travel pattern and our crews will be closely monitoring traffic when the interchange reopens Monday morning. We will adjust traffic signal timing to ensure traffic is moving efficiently through the new interchange.”
Yeager added that motorists should continue to use caution in the project area. “Even though the new travel pattern will be in place, this will still be a very active construction area with crews continuing to work on ongoing improvements," he said. "Please be mindful of crews working in the project area through the remainder of the year.”
The graphic below represents the final traffic configuration of the double crossover diamond interchange when work is completed.

The overall project is expected to be completed by November 2023.
The date, time, and duration of work may be adjusted if inclement weather or other unforeseen delays occur. Motorists can get Northern Kentucky road construction updates on the District 6 Roadshow.
