The tunnel was originally known as the Sunset Tunnel until 2002. It was renamed in honor of Dennis L. Edwards, an Oregon Department of Transportation worker who was killed on January 28, 1999 when part of the tunnel collapsed while he was inspecting it for damage caused by heavy rains.[3] The tunnel was closed for five weeks for repairs,[4] and renamed for Edwards three years later.[5]
