Design Development Phase – Virtual Public Information Center


The purpose of this project is to construct an amphibian passage system along a 1,200-foot section of Waterloo Road and the surrounding Allamuchy Mountain State Park and Waterloo Village lands in Byram Township, Sussex County. The project offers a long-term solution to the vehicle-caused mortality threatening a significant local population of amphibians that must migrate across Waterloo Road to reach their nearby vernal breeding pond each spring.

Improvements include:

  • Construction of four (4) specialized amphibian tunnels beneath Sussex CR 604 – Waterloo Road
  • Installation of guide fencing on both sides of the road to intercept and funnel amphibians towards the tunnels



Design Development Phase Completion: Summer 2021
Final Design Phase: Summer-Fall 2021 2022
Construction: 2022 2023
