Requires DOT to establish program for construction of wildlife crossings on certain roads and highways.

New Jersey's A1683 requires the Department of Transportation (DOT) to create a program for building wildlife crossings - like tunnels, overpasses, or fenced pathways - on state roads. The DOT must prioritize projects on high-collision roads or those fragmenting habitats of threatened/endangered land animals, publishing this list within 12 months. Within 24 months, the DOT must begin constructing at least one priority project and continue until all listed projects are completed. The bill also mandates seeking federal grants (under the Infrastructure Investment and Jobs Act) and including annual funding requests for the program in future budgets.
