New I-84, Ten Mile Interchange will open Wednesday afternoon (May 25)
MERIDIAN - Motorists can try out the new I-84, Ten Mile Interchange on the way home from work Wednesday (May 25). Weather permitting, the Idaho Transportation Department will pull traffic barriers and activate the signal by 5 p.m. for the evening commute.
The new interchange will serve western Meridian, Kuna and eastern Canyon County. It is expected to relieve congestion on surrounding roadways and interchanges.
The interchange design, called a "single point urban interchange," is similar to the new Vista Interchange in Boise. ITD distributed a flier with driving tips to businesses and residents in the immediate area.
Traffic engineers say the design is more efficient for drivers because all turning movements are controlled by a central set of signals. Motorists only stop once at the center of the interchange, instead of twice as at other interchanges.
"The interchange design is a good long-term choice for Meridian," said Jason Brinkman, GARVEE Program Manager for ITD. "The engineering analysis showed that the design created fewer delays and improved efficiency when compared to a traditional diamond interchange design."
A map of the new interchange ramps is available at www.itd.idaho.gov/projects/d3 under Ten Mile Interchange.
All four through lanes of Ten Mile Road will be open on Wednesday when the interchange opens. Occasional lane restrictions will continue on Ten Mile Road during the landscaping work this summer.
Construction will continue on I-84 during the summer while crews place permanent concrete under the new interchange. One eastbound and one westbound lane will be closed for several weeks in June and July. All construction is expected to be completed in August 2011.
