Overview — frequently asked questions
How is this project related to other regional Mississippi River crossing improvements?
Is this project focused only on the I-74 bridges over the Mississippi River?
How long did this study last?
- 1998: Mississippi River Crossing Study
- 2000: I-74 Corridor Study began
- 2003: Draft Environmental Impact Statement completed
- 2005: Preferred Alternative identified
- 2006: Main Span Bridge Type chosen
- 2007: Preliminary Engineering completed
- 2009: Final Environmental Impact Statement completed and Record of Decision received from the FHWA
Are the problems along I-74 that serious?
Could the I-74 congestion problems be fixed without the build alternatives?
Could the problem be remedied by simply improving the ramps?
Would diverting interstate through traffic fix the congestion problem?
Can the existing Mississippi River bridge be widened?
What will happen to the existing Mississippi River bridges when a new
I-74 river bridge is constructed?
The decision on the fate of the existing bridges was made during the FEIS phase, following public input. Options to keep the bridges in place were considered, including an option to keep one of the bridges in place for an alternative transportation use (bicycle/pedestrian). However, in order for the alternative transportation use option to be implemented, a public agency must be willing to assume jurisdiction of the bridge, and be responsible for its ongoing maintenance. Involved local agencies have indicated that they are not interested in assuming future responsibility for the existing bridge. Options to use the bridges for other vehicular purposes were eliminated during the FEIS phase of the study. With the roadway and bridge type selected the existing bridges would be dismantled as part of the construction of the new bridges.
Will the project result in impacts on historic properties in the area?
Now that the study is complete, will construction begin?
Now that the Final EIS and the Record of Decision are complete final design can begin. Funding is secured through final design and through some of the right-of-way acquisition. Funding must still be secured for the remaining right-of-way acquisition and the actual construction of the proposed improvements. Once funding is secured and final design and right-of-way acquisition is complete (final design alone is a three year effort) major construction efforts on the new Mississippi River Bridge and approaches could begin. However, there are independent projects within the I-74 corridor that are already in Iowa’s Five Year Transportation Improvement Program. These include the Lincoln Road bridge over I-74 in Bettendorf and the 53rd Street interchange in Davenport.
What types of improvement alternatives were considered for I-74?
|Roadway capacity improvements. Capacity improvements allow more vehicles to travel on the road. These improvements included the expansion of the roadway with additional travel lanes, and improvements to interchanges and intersections.|
|Roadway design improvements. Design improvements enhance the operation of the facility. These improvements included improving the alignment of the roadway, providing wider travel lanes and shoulders, and improving the location and design of on- and off-ramps.|
|Transportation system management. These actions are usually designed to improve the operation and performance of the existing system, and included intersection improvements that accommodate turning movements, travel advisory signs, and traffic signal coordination.|
|Transit improvements. These actions could include improvements to the regionsí transit systems. Improvements could expand services, or enhance existing services by providing features such as bus turnouts or more frequent service.|
|Bicycle and pedestrian improvements. There are a number of bicycle and pedestrian facilities in the project area. Opportunities to enhance connections across or along highways in the study area were considered. This will include options to improve bicycle and pedestrian access across the Mississippi River.|
How will community values and interests be preserved with this project?
- continuous two-way dialog throughout the study with area community officials
- thorough review of local land use and comprehensive plans, county plans, and regional plans to ensure consistency with alternative solutions
- input from community and neighborhood groups on local issues
- consideration of community issues in the development and evaluation of alternative solutions for the corridor
