Alternatives

  • Study area was

divided into seven subareas

  • The current study is

focusing on the two main subareas

– Subarea 1 (CR 14) – Subarea 4 (Interchange Location)

  • Subarea 1
  • Potential connection to

planned Cannon Falls route

  • n the north
  • Alternatives 1.B and 1.C

use a new alignment

  • Alternatives 1.B.1 and 1.B.c

cross challenging topography

  • Alternative 1.A uses an

existing rout with many residential driveways
