50th Street and Grange Rd Improvements

The Eden Grange Roundabout Project is starting on May 8. Willson Road will be closed south of Eden Avenue beginning May 8. Look for a signed detour route utilizing Eden Avenue, Benton Avenue and the West Frontage Road. Access will continue to be provided to local residents and businesses along the East Frontage Road. Sidewalks will also be closed as it will not be safe to enter an active work zone. Please refrain from cutting through the active work zone. We continue to have problems with pedestrians and cyclist entering active work zones at other locations. This is not safe. The work that is anticipated in May includes relocations of private utilities. Installation of watermain, and concrete curb & gutter.

We opened bids last week and have a preferred contractor to complete the project this year. Staff is asking the City Council and HRA to approve contracts this week. A detailed construction schedule will be coming soon. Generally, Willson Rd south of Eden could be closed early May and the entire intersection closed early June after school is out for the summer. The project is required to be completed by the end of August before school starts in the fall. Thank you.

The preliminary layout for the roundabouts at Eden and Grange have been developed as shown above. The consultant is working on vertical alignments and construction limits. After those details are available, staff will communicate those details and be available for questions. Thanks, Chad Millner, City Engineer.

Staff will be presenting the final concepts and community feedback on those concepts to the City Council on Nov. 3. The item is informational only and not open to public testimony. Thanks, Chad Millner, City Engineer.

Please find a graphic for concepts outside of the TIF district. We are calling these Phase 2 Improvements. Typical street funding sources would have to be used to construct these improvements. The funding has not been identified and these are not in the 5-year Capital Improvement Plan.

Thanks, Chad Millner, City Engineer

Please find a graphic of all three concepts being considered. We are calling these Phase 1 Improvements. These would most likely be eligible for TIF Funding.

The concept on Grange Road will modify existing traffic lanes and adding a wide shared use trail on the west side. The benefits of this concept are;

1. Reduced Vehicle Speeds - traffic calming by narrowing lanes.
2. Improved pedestrian facility - wide shared use trail.
3. Fills a gap in the pedestrian network between Eden Avenue and 50th Street.

Thanks, Chad Millner, City Engineer

The concept on 50th Street is a 3/4 access intersection at Dale Dr and the City Hall entrance with protected left turns, right in - right outs, and expanded off street pedestrian and bike facilities. It also improves the traffic signal at 50th Street and Grange Road. The benefits of this concept are;

1. Reduced vehicle and pedestrian conflict points from 32 to 10.
2. Safe queuing for left hand turns within dedicated medians.
3. Reduced Vehicle Speeds - medians provide traffic calming by narrowing lanes.
4. Reduced severity and frequency of most crash types.
5. Improved pedestrian facility - wide shared use trails on both sides.

Thanks, Chad Millner, City Engineer

The improvement concept at the intersection of Eden Ave, Grange Rd, and Wilson Rd is 2 roundabouts. Because of the offset nature of the intersection and the proximity to driveways, 1 roundabout does not work at this location. The benefits of this concept are;

1. Reduced Vehicle Speeds
2. Reduced vehicle and pedestrian conflict points.
3. Reduced severity and frequency of most crash types.
4. Improved pedestrian facility - wide shared use trails on both sides, shorter crossing distances, median refuge island, crossing only one direction at a time.
5. Typically, less delay than traffic signals or all-way-stop intersections.

Thanks, Chad Millner, City Engineer
