Missman, in conjunction with HNTB Corporation and Quigg Engineering, Inc., will provide construction engineering and inspection services to the Iowa Department of Transportation. This project will consist of the I-74 approach spans over the river on both sides of the main arch span bridge; the main arch span bridge; westbound Iowa viaduct; and the westbound exit ramp to US 67.
The Interstate 74 Bridge Corridor project involves the replacement of the I-74 Bridge and nearly eight miles of corridor improvements. The proposed improvement of the I-74 corridor in the Quad Cities extends from south of Avenue of the Cities in Moline, IL to north of 53rd Street in Davenport, IA. Also included are some corridor-wide supply and installation projects. Construction work is expected to be completed by the end of state fiscal year 2021 for this section. For the north section, final design efforts have just begun.
Construction on the new bridge will begin in the water in summer 2017. Work in the river will continue throughout the project. The approaches will be constructed in 2019 and 2020 with the old bridge set for demolition in 2021.
Missman is honored to be part of this vital transportation project for the Quad Cities. The cost for the entire 7.8-mile corridor is approximately $1.2 billion.
Missman provides civil and structural engineering, and land surveying/land acquisition consulting services to local and state agencies, and private clients throughout the Midwest.
