Cole Road Concept Design

General Description:

The Cole Road Project is now in the process of being designed.


The Cole Road Concept Design was adopted by the ACHD Commission on January 9, 2013.

The concept design report proposes widening Cole Road between the I-84 Interchange westbound on-ramp and the Franklin Road intersection to five lanes, widening the Cole and Franklin intersection, exploring a connection road from Cole Road to Auto Drive, just north of the Harrison Hotel, and recommends the west option for realigning the intersection at Cole and McMullen.

What are the challenges for this project?

  • Impacts to adjacent property owners & neighborhoods
  • Canal
  • Utilities expensive to move
  • Business and neighborhood access
  • McMullen/Cole intersection
