PIERRE, S.D. (KELO AM) – The South Dakota Department of Transportation is pleased to announce the 2013 Interstate 90/Cliff Avenue reconstruction project in Sioux Falls has won regional acclaim in the America’s Transportation Awards competition, sponsored by the American Association of State Highway Transportation Officials (AASHTO), AAA and the U.S. Chamber of Commerce.
The South Dakota Department of Transportation won the award in the Best Use of Innovation category for a small project. The department won an award in the same category for a medium sized project last year for the 2012 Mitchell to Chamberlain Railroad rehabilitation project.
The $17.4 million I-90/Cliff Avenue interchange project included reconstruction of 3,800 feet of Cliff Avenue and one mile of I-90, and the replacement of two bridges over Cliff Avenue. The interchange was converted from a typical diamond intersection to a single-point interchange which reduces conflict points and increases safety for the traveling public.
This project was one of the first in the nation to utilize innovative mobile temporary traffic signals to accommodate the various phasing of the project. This helped minimize the impact to the traveling public during construction and saved the contractor time and money by not having to move a semi-permanent signal system up to 10 times during the project.
“This was an important project to enhance and upgrade the state’s transportation system,” says Darin Bergquist, Secretary of the Department of Transportation. “The exponential growth in this area of Sioux Falls and the large volume of truck traffic necessitated new pavement, new bridges, wider turn lanes and upgraded traffic signals to relieve congestion and provide a safer roadway for the traveling public.”
This project was a great example of collaboration between the Federal Highway Administration (FHWA), South Dakota Department of Transportation and the City of Sioux Falls.
