The open house will be informal allowing for one-on-one discussion with the study team. A brief presentation will be given at approximately 5:40 p.m. The purpose of the meeting is to present alternatives that have been further refined, analyzed, and evaluated following the first public meeting. The meeting will also present preliminary interchange and I-29 mainline recommendations for public review and feedback. Area residents, business owners, and daily commuters are encouraged to attend and participate in the study. The opportunity to present written comments will be provided. Written comments will be accepted until Friday, Dec. 17, 2021.

For those who cannot attend the open house or desire additional information on the overall study, a virtual component of the public meeting will also be available at the study website beginning on Tuesday, Nov. 30. 2021.

The meeting presentation will be streamed live through a link on the study website. Meeting materials and a recording of the presentation will be posted to the website following the public meeting. The website also allows for online comments to be submitted.
