04.26.17 I-84 Meridian Road Interchange Receives Engineering Excellence Award from ACEC

Meridian, ID - On Tuesday, April 25, 2017 the American Council of Engineering Companies (ACEC) recognized the I-84 Meridian Road Interchange project with a 2017 Engineering Excellence Award. The ACEC’s annual Engineering Excellence Awards (EEA) competition recognizes engineering firms for projects that demonstrate a high degree of achievement, value, and ingenuity. The award was presented to Parametrix, the prime consultant responsible for project management, permitting services, engineering design, and construction services, as well as the Idaho Transportation Department (ITD), at ACEC’s annual black-tie EEA gala in Washington D.C.

The I-84 Meridian Road Interchange project replaced a severely over capacity diamond interchange with a new Single-Point Urban Interchange (SPUI) and reconstructed over four miles of interstate to provide additional capacity, improve safety, and extend the design life of I-84. The interchange is currently the second busiest in the State of Idaho and the new SPUI will accommodate years of future growth; it is designed to handle 284,000 vehicles per day, well over the current 125,000-plus vehicles per day. This project also improved capacity of I-84 in both directions, adding an additional lane in each direction and removing one of the last “bottleneck” areas of the I-84 corridor from Boise west to Nampa.

Considered the gateway to the City of Meridian, the additional capacity that this project provides will help the City of Meridian attract more businesses. By completing one of the last links in the I-84 corridor from Boise west through Meridian to Nampa, the project impacts the entire Treasure Valley and beyond as I-84 is the only U.S. interstate that serves Southwest Idaho.

The I-84 Meridian Road Interchange is an important project that exemplifies the Idaho Transportation Department’s mission to improve safety, mobility, and economic opportunity. This project also exemplifies the benefits of consultant and agency design teams working together to accomplish a significant project. The consultant team led by Parametrix was responsible for design of the interchange and an internal ITD team was responsible for design of the improvements to I-84. Through skillfully coordinated efforts, the two teams worked extremely well together to combine the two sets of construction documents into one set of plans for construction in just 10 months, a very aggressive schedule.

In a letter to ACEC supporting the nomination, Amy Schroeder, ITD District 3 Engineering Manager, said:

“Design time for the project was extremely condensed to take advantage of limited available funding. Parametrix and their consultant team were responsible for design of the interchange while ITD was responsible for designing improvements to the interstate. This required intense collaboration to combine two independent designs into one cohesive bid package… These are just a few examples of the resourcefulness and talents of the combined Parametrix and ITD design team that is worthy of an Engineering Excellence Award.”

In addition to Parametrix, the consultant team included HNTB for structural design, T-O Engineers for surveying and right-of-way, and GeoEngineers for geotechnical engineering. The general contractor was Concrete Placing Co.
