Bob Ortblad scrutinizes IBR ramp design
Editor’s note: Opinions expressed in this letter to the editor are those of the author alone and may not reflect the editorial position of ClarkCountyToday.com
Three years ago, I created and posted a graphic of a possible “Shared Use Path.” The graphic accurately depicted the difficulty of a 100-foot climb to the bridge level. Interstate Bridge Replacement Program (IBR) officials were not happy with my depiction and promised to consider future multiple ramp designs.
The latest of these designs was presented at an IBR workshop on August 27, 2025, by Knight Architects, a costly firm from London. Knight’s design has a grade of 4%, is about a half-mile-long, with turns totaling 810-degrees.
A small model of the shared use path was presented to an IBR architectural advisory group in October.

Knight Architects’ ramp design may have been inspired by a Disney Cruise water slide. For an average walker or biker, the distance, grade, and turns will make the climb exhausting and disorienting. The descent will be terrifying. Knight Architects has a $1.4 million contract; how much was wasted on this flawed design and model?
