128th Ave. & Cook Cir.

Thornton, CO


Working with partner firm Huitt-Zollars, MTJ provided a peer review and develop optimized final horizontal geometrics for this challenging, constrained intersection. The MTJ corrective design ensures optimal safety for all modes and community acceptance once constructed.


MTJ provided Rodel analysis and sensitivity testing to meet long-range operational objectives. The final laneage/design reduced the number of conflict points – improving safety and feasibility for this site.

Working with the project team (City and Huitt-Zollars) the final MTJ optimized re-design ensured adherence to foundational safety design principles for safety, while maintaining acceptable impacts with respect to ROW, grades and impacts on surrounding land uses.

The MTJ design process started with development of alternative sketches, then concept designs allowing for evaluation and determination of the final horizontal geometric design.


  • Reduced number of conflict points
  • Maintained acceptable impacts to ROW and surrounding land uses
  • Optimized safety for all modes
  • Skewed, constrained context
