Giss Parkway interchange at Interstate 8 opens in Yuma

ADOT project creates area’s first freeway modern roundabout

Freeway Interchange roundabout at Giss Parkway, YumaYUMA – The Yuma area’s first modern roundabout for a freeway interchange has opened at the Giss Parkway ramps connecting with Interstate 8.

Some work remains on the $2.5 million project to replace a T intersection for the on- and off-ramps from westbound I-8, the last exit before drivers reach the Colorado River. The project also includes improved lighting, signage and drainage, as well as accommodations for cyclists.

Work began in March and will be completed this fall.

“Modern roundabouts are designed to move traffic more efficiently without the use of traffic lights,” said Paul Patane, ADOT’s Southwest District engineer. “ADOT has used modern roundabouts in other parts of the state, and they have proven to move traffic smoothly and safely without the long delays that can come with traffic signals and stop signs.”

ADOT crews also are constructing two modern roundabouts at Araby Road in Yuma.
