The Federal Highway Administration (FHWA) has indicated a preliminary finding that the proposed bridge replacement project on Hwy 30 in 2023 would have minimal impact on the environment at Mill Creek. However, it will consider public comments prior to its final determination on environmental impact.

This comment period closes April 5, 2022. If you have comments, please send them to MnDOT project manager Jake Gasper. All comments made during the comment period will be reviewed and considered.
