The California Transportation Commission approved allocation of funds for three wildlife overpasses across Interstate 15, a project supporters said is essential to reconnect habitat in the Mojave Desert and to reduce vehicle‑wildlife collisions.

Speakers from conservation organizations and academic institutions urged approval. Neil Desai (National Parks Conservation Association), Megan Cleveland (The Nature Conservancy) and Elizabeth Reed Wainscote (Center for Biological Diversity) described ecological and climate resilience benefits, and Clint Epps, a wildlife biology professor, emphasized the barrier effect of I‑15 on species such as bighorn sheep.

Commissioners framed the decision as a safety and conservation measure. Commissioner Guardino noted that collisions with wildlife threaten drivers as well as animals and stressed the broad social benefits of the investment. The commission approved the request and commissioners praised the multi‑agency and multi‑stakeholder collaboration that delivered the project to construction readiness.

Next steps: Caltrans District 8 and partners will proceed with construction procurement and community outreach; environmental compliance and monitoring plans will guide post‑construction evaluations of wildlife movement benefits and vehicle collision reductions.
