The Interstate 35 West bridge across the Mississippi River will glow blue for 11 days in honor of Jacob Wetterling.
Minnesota Governor Mark Dayton on Wednesday ordered the bridge to be cast in blue light starting Friday.
Jacob was 11 when he disappeared near his home in St. Joseph and sported the number 11 on sports jerseys.
The blue lights represent child abuse prevention.
Jacob was abducted on October 22, 1989. After nearly 27 years of cold leads and mystery, Danny Heinrich recently confessed to abducting, sexually assaulting, and killing him.
Heinrich led authorities to the field in Paynesville where Jacob's remains were recovered last month. Jacob's memorial service will be held September 25. That's when the blue light memorial will finish.
