Operating Constraints & Field Realities
The US-93 corridor through the Flathead Indian Reservation intersects vital migration corridors for grizzly bears, elk, and white-tailed deer, resulting in historical collision clusters.
While the physical crossing structures represent a milestone in ecological highway design, regional contractors and engineers needed practical data on post-construction maintenance, wing-fence upkeep, and winter drainage.
Engineered Countermeasures & Delivery
The association hosted specialized technical site inspections and field roundtables with maintenance managers to document long-term structural resilience.
We published a practitioner guide addressing aggregate settlement on overpasses, wildlife-proof gate durability, and seasonal runoff management around culverts.
