The I-74 Mississippi River Bridge historically has provided an important east-west link in the nation's transportation network.
The I-74 Mississippi River Bridge project is part of a regional strategy for improving access across the Mississippi River in the Quad Cities. It includes the replacement of the I-74 bridge over the Mississippi River as well as interchange ramp reconfigurations and local roadway improvements. Construction began in July 2017 and is anticipated to take place over 3 1/2 years. The new bridge will be more than twice as wide as the existing bridge, providing four lanes in each direction. A multi-use path on the bridge will connect to paths in Bettendorf and Moline.
Hatcher Technical worked with construction engineer McNary Bergeron and the contractor to provide:
- Fully integrated conflict free 3D models of the cast in place concrete arch base and cross beams
- A constructability review to assess the integration of the steel arch embedded anchor assembly, cross beam PT and reinforcement and the concrete arch base reinforcement
