Thanks to early planning and a simple innovation, mice, green frogs, and other small animals can continue their movements along the banks of a stream in Pawtucket, Rhode Island's historic Slater Mill Park. When a Rhode Island Department of Transportation design team planned a modified box culvert to carry the Ten-Mile River Bikeway across the stream, they added shelves to the inside of the culvert, slightly above the water surface and parallel to the stream. Wildlife species can continue their path along the water, and since the shelves were added to the culvert design before construction - not added later after the culvert was built - they contributed very little to the project cost.
