About this project

This project removes the over 120 year old Bassett Creek tunnel that is no longer in use; a new tunnel was constructed to replace the old one in 2018. The project also replaces aging pavement on Hwy 55, which achieves MnDOT’s goal of maintaining a safe, efficient, accessible and reliable multimodal transportation system that connects people.

Summary of work

  • Remove remainder of deteriorating tunnel formerly carrying Bassett Creek under Hwy 55
  • Line/reconstruct 24 inch underlying sanitary sewer constructed below tunnel
  • Remove/replace pavement on Hwy 55
