The viaduct is just part of 1.33 miles of construction that will connect traffic with Snowy Range Road, WYO 230 and also widen the Laramie River Bridge to four lanes.
Patrol Sgt. David Wagener notes that Hansen was the 17th person killed on a motorcycle this year, compared with 18 motorcycle-related deaths during the same period in 2015.
Thursday's celebration is, of course, open to the public. Refreshments will be served after the brief ceremony, and the community will be able to tour the new Laramie High School.
