State’s First Diverging Diamond Receives Engineering Award
I-69 interchange at S.R. 1 earns Honor Award for Engineering Excellence

(November 24, 2015) – The Indiana Department of Transportation announces the diverging diamond interchange at Interstate 69 and State Road 1 in Fort Wayne has earned an Honor Award for Engineering Excellence by the American Council of Engineering Companies of Indiana.

ACEC presents the Engineering Excellence awards to recognize outstanding engineering achievements that demonstrate a high degree of merit and ingenuity. The I-69/S.R. 1 DDI is one of eight projects to earn Honor Award designation and will vie for the ACEC Grand Project Award, to be announced in March 2016.

In April, the DDI was named the Civil Engineering Project of the Year by the American Society of Civil Engineers Indiana section.

Designed by Burgess & Niple, the interchange modification project was built to add traffic capacity and relieve congestion for an estimated 40,000 motorists who travel the interchange each day. The redesigned interchange has also improved access for emergency vehicles to the two hospitals in the area.

Additionally, the $3.5 million project features a barrier-separated median designed for pedestrians. It has proven to be a safer path for pedestrians to navigate the interchange and connect to Fort Wayne’s existing trail network.

  1. “the interchange modification project was built to add traffic capacity and relieve congestion for an estimated 40,000 motorists who travel the interchange each day. The redesigned interchange has also improved access for emergency vehicles to the two hospitals in the area.”

    What is missing from this article? Pretty simple, no where does it state that the objective was achieved. In addition, it does not mention that the timing of lights now require drivers to stop at nearly every stop light between Auburn Road and the Carmike/Parkview stop lights. The speed limit has been reduced, thus reducing capacity. The shortened cycle time of the light has added additional down time for traffic versus the previous longer cycle time which would have allowed more cars per second of cycle time to traverse.

    Stop and go is less efficient. I have not see any improvement, just the opposite. Does anyone have an objective value to present?
