The state Department of Transportation is working on unusual interchanges designed to relieve congestion at high-traffic areas across the state.
Crews are building seven intersections known as Diverging Diamond Interchanges. They temporarily move traffic to the left side of the road before dumping them onto the freeway or shifting back to the right to cross the intersection.
DOT engineer James Dunlap says it makes getting on and off the freeway easier.
"It's a free-flow left, so once you get past the first signal, you're not stopping again," Dunlap explains.
