About this project

Why this project is needed

  • Existing and future operation of interchange which is characterized by inadequate spacing between intersections
  • Future operation of Hwy 29 south of I-94 as area continues to grow
  • Traffic congestion along 50th Avenue


This proposed project is the result and recommendation that was brought forward from the Alexandria Area 2030 Transportation Study (completed in March 2011).
