The accolades keep mounting for the reconstruction project at the I-84, Vista Interchange in Boise.
The project is rebuilding the Vista Interchange (the bridge was built in 1969) with a Single Point Urban Interchange (SPUI) design. That design places a traffic light at the center of the interstate bridge and allows for protected left turns in each direction. The new interchange will have two through lanes in each direction and dual left-turn lanes. On- and off-ramps will be widened and lengthened to improve traffic flow. The new bridge also will accommodate the expansion of I-84.
“I have designed SPUIs before; that wasn’t the main challenge,” explained Bob Jacobs, project manager for Stanley Consultants. “The challenging aspect was doing it in nine months, while still meeting project milestones. That’s unheard of.”
ITD’s District 3 design on Vista was started by Sue Sullivan and finished by Wade Christiansen. Jason Brinkman, GARVEE Program Manager, also was key to the project.
Jacobs also said cooperation among design team members, Connecting Idaho Partners, ITD, the Ada County Highway District, the city of Boise, and the Boise International Airport “made possible the rapid delivery of this quality project.”
In addition to receiving the ASCE award, interchange project received the Women in Transportation Society (Treasure Valley Chapter) Innovative Engineering Solutions Award, the ITD/CIP Performance Award, and the ITD 2010 Excellence in Construction Award.
