St. Louis County is leading a corridor study of CSAH 100 (3rd Ave N/Main St), beginning at a point 0.22 mile east of MNTH 135 and ending at CSAH 110 (Hwy 110), for a total length of 1.83 miles in the City of Aurora. The outcome of this study will be the preferred corridor layout which will be used for the planned reconstruction project on this corridor in 2026. This study is anticipated to be completed by this December 2024.

The key focus areas of the corridor study include…

  1. Complete an intersection control evaluation (ICE) of Main St and 3rd Ave N. The ICE will recommend a long-term intersection control strategy.
  2. Develop a typical section(s) for the CSAH 100 corridor.
  3. Develop a 2D (aerial view) layout for the CSAH 100 corridor.
