On the first rainy night above freezing in spring, salamanders move from the uplands where they over-winter down into the wetlands to breed.

Prior to construction, a five year study was done to see where and how frequently salamanders crossed Monkton road.

Survey results found a significant population of salamanders using this crossing. However, during peak migration over 50% of salamanders were not surviving the crossing.

To increase their survival rate, two amphibian friendly culverts were constructed for salamanders as well as other wildlife.

Recycled concrete blocks were used as fencing to line the highway and ensure wildlife made it to the tunnels.

Concrete fencing extends approximately 100 feet on either side of the culverts.

Concrete fencing extends about 100ft on either side of the culverts.

Grates allow sunlight and moisture to pass through the culverts. Light is critical in aiding wildife through the structures.

The Mink on the right can clearly see the light at the end of the tunnel...

Monkton Road

The first wildlife crossing on Monkton Road is located 1/2 mile East from the intersection with Nichols Road.

2nd Wildlife crossing

Located 1/3rd of a mile up the road from the 1st crossing.

Wetland

Mating habitat for salamanders in the spring.

Post construction, a five year study was conducted to evaluate the effectiveness of the culverts.

The crossings were hugely successful in faciliating the movement of thousands of salamanders. Road mortality rates dropped by 93%!

Watch them go during peak migration in the time lapse video on the right!

The tunnels are also used by other wildlife, like this bobcat.

  • A Vermont Agency of Transportation/Federal Highway Administration Transportation Enhancement grant provided $150,000 toward construction.
  • Vermont Fish and Wildlife State Wildlife Action Grant accounted for $45,000.
