Deer Roadkill (HSUS). Accidents between motorists and wildlife pose a safety risk on our roads. Between 1991 and 2001 over 240 ungulates (deer and elk) were killed by motorists on just the 15 mile stretch of this project area. |

Black Bear on Fence (WSDOT). Fencing aids in directing wildlife to the crossing structures, but is not a fool proof barrier. Due to the topography at Snoqualmie Pass, new techniques and considerations are being used for fencing. |

Bald Eagle (Conservation NW). Bald eagles and other raptors such as turkey vultures are drawn to road kill along Interstate 90. While fighting over the dead animal, they can be hit by motorists. The Forest Service biologist for this area says that this is often the reason for the calls that she receives of injured bald eagles along I-90. |

Elk on Overpass (American Wildlands). Hard to see in this photograph is an elk standing on top of a wildlife overpass. Elk are large ungulates related to deer. They have white tails, reddish-brown bodies, and large spreading antlers (which are shed each year). Often seen in national parks, usually in groups of 25 or more; but are also seen frequently in the central Cascades. Elk feed on grasses, herbs, twigs, and bark. They migrate up mountains in the spring and return in the fall. Males have a haunting, high-pitched bugling call used in mating in the fall. Elk live 14-25 years. They are also a key prey species for predators such as wolves and mountain lions. They use the Banff underpasses more often than any other species. |

Salamander Crossing Sign (FHWA). Salamanders, as well as other amphibian and reptile populations often suffer greatly when their habitat is near highways and roads. This sign was created to alert drivers to salamander movements across a road which typically occurs during the spring breeding season. |
