Excerpts from wkow.com:

A bill was signed on Thursday renaming the Sun Prairie post office after Sun Prairie FD Captain Cory Barr who was killed in a natural gas explosion in downtown Sun Prairie in July 2018.

Workers installing fiber-optic cable triggered the explosion when they mistakenly struck an underground gas line. Barr was among a group of firefighters who evacuated more than 100 people from the area ahead of the blast. Six buildings were destroyed but no one else was killed.

The bill was introduced in April, the Senate passed it in July, and the House passed it Oct. 16.
