While working at a previous firm, Jon Altschuld developed the Aesthetic Design Guidelines for the I-25/Cimarron (US-24) interchange design-build bid package. Converting this dated and overused interchange to a modern Single Point Urban Interchange (SPUI) required heavy stakeholder involvement from multiple government agencies concerned about aesthetic, environmental, and public relations impacts.

The project included the restoration of approximately 2,100 linear feet of Upper Fountain Creek immediately upstream of its confluence with Monument Creek. This restoration required re-grading of the creek banks, vegetation of newly created riparian and upland areas, re-alignment of the main channel, and a strategic balance of vegetated and structural bank stabilization to protect infrastructure while improving ecological functions.

Jon also led the design of the aesthetics for all bridge structures, the overall site design, trail alignments, and custom formliner 'fish' panels along the regional trail.
