Alternative Intersection/Interchange Designs
The diverging diamond interchange is a relatively new concept in freeway
interchange design. The Missouri Department of Transportation recently reconfigured the interchange at Route 13 and I-44, replacing a diamond interchange with the diverging diamond configuration. This type of ramp system prioritizes entering and existing traffic by
making those movements free flow. The through movements “cross-over” at the
overpass, and the entire system is handled by a two-phase traffic signal that dictates
the flow of the through movements.
Proposed “Freedom Roads” Trail
To commemorate routes used by freedom seeking African Americans from the antebellum period to the end of the Civil War
“Freedom Roads” will recognize roads, rivers, and ports along North Carolina’s Scenic Byways* that were critical to the efforts of enslaved African Americans seeking access to freedom, and those who supported these freedom seekers. “Freedom Roads” will specifically highlight freedom seeking via the Underground Railroad as well as avenues of liberation created during the Civil War.
