The Des Moines Southwest Infrastructure and Planning Study is being completed to review existing infrastructure and develop recommendations to improve the transportation network to support future traffic demand from south of Des Moines, future development west of the Des Moines International Airport, and redevelopment opportunities that may occur along Bell Avenue and Thomas Beck Road. A Land Use Master Plan for the area south of Gray’s Lake and a drainage analysis for a wetland identified in the Gray’s Lake Master Plan are also being completed in conjunction with this study. An overview of the planning study areas is shown below.
Infrastructure recommendations will be made to:
- Maximize use of existing Highway 28 and Park Avenue improvements west of George Flagg Parkway to support increasing regional traffic.
- Improve reliability of George Flagg Parkway to better serve commuters, freight, and emergency vehicles including traffic operations at the intersection with Park Avenue.
- Recommend alignment modifications that connect George Flagg Parkway to Bell Avenue at SW 30th Street.
- Improve Bell Avenue and Thomas Beck Road to support future redevelopment.
- Integrate recommendations for bicycle and pedestrian network throughout the study area.
- Develop a concept design and cost estimate for the Gray’s Lake Wetland identified in the Gray’s Lake Master Plan.
What has happened so far?
The Southwest Infrastructure study was started in 2020. To date, the project team has completed existing data collection, traffic operations analysis, and developed conceptual recommendations. A project stakeholder group was conveyed as part of the planning process to explore various constraints and opportunities along the corridor and how future recommendations could address them.
An overview of the recommended network and roadway typologies is shown below.
On July 28, 2021, a public open house was held to share concept recommendations for future improvements to the transportation network. Approximately 90 people attended the public open house. Information about various road segments and alternatives were presented for visitors to review and provide comments. The project team and city staff were on-site to answer questions and facilitate discussion about the concepts.
The Open House Station boards and Station Guides may be viewed below. Questions or comments about the open house material may be sent to City of Des Moines Principal Traffic Engineer Corey Bogenreif, PE at ENG-TT-ENG@dmgov.orgDownload materials
What are the next steps?
A summary of the open house material and public comments will be presented during a City Council work session August 9, 2021. The final study report will be completed in September 2021 and will include a prioritized list of recommended projects and planning level cost estimates.
The South of Gray’s Lake Master Plan is scheduled to be presented to the City Council September 13, 2021. Click below for more information about the South of Gray’s Lake Master Plan.South of Gray’s Lake Master Plan
