Overview of Past Progress

  • Decided to proceed with new two-lane river crossing in

current location

  • Completed Bridge 9103 Rehabilitation Study
  • Identified and refined recommended set of concepts for the

MN and WI approach roadways

  • Identified three recommended river bridge types

Tied Arch

  • Least approach roadway

impacts

  • Requires periodic painting
  • Moderately complex

construction & inspection

  • Highest construction cost

Segmental Concrete Box Girder

  • Greatest approach roadway

impacts

  • Does not require painting
  • Simpler construction &

inspection

  • Most cost effective structure

Next Steps

  • Continue drilling and environmental investigations;
  • Complete evaluation of the Minnesota approach alternatives

and the three bridge types;

  • Obtain public input;
  • Identify the recommended Minnesota approach option and

river bridge type;

  • Proceed with the Environmental Assessment (EA)
