Industry Remembers Caltrans “Trailblazer”

ACPA is mourning the passing of Kirsten Stahl, District Materials Engineer with Caltrans.  She died unexpectedly last week.  

We remember her as someone who was not only well respected by her staff and colleagues, but also by those of us in the industry who worked with her on pavement projects.

Over her career, Kirsten was an energetic participant in several pavement preservation activities of ACPA and IGGA, and was considered among the most open to innovation and embracing new ideas, said Jerry Voigt, ACPA President & CEO. She was involved with pioneering rapid reconstruction and repair techniques for pavements around Los Angeles, where she worked for Caltrans District 7. 

“Her input as an agency representative was always welcome and she was always appreciated for her desire to advance ideas.  She had a very refreshing ‘can do’ nature,” Jerry remembers. 

Jerrel Kam, District 7 Deputy Director for Design said she and a colleague were recently instrumental in trailblazing the use of precast concrete panels, which are now a standard for repairing some of the most heavily trafficked freeways in the nation.

Kirsten came from an important lineage within Caltrans.  Her mother, Marilyn Jorgenson Reece, a Senior Transportation Engineer, was the first female registered engineer in the State of California. Her father Alvin was a Caltrans Transportation Engineer before moving on to the County of Los Angeles, and her late husband Stewart Stahl, was a 40-year Transportation Engineering veteran and well respected designer in Caltrans’ District 7.  Her father-in-law Ernie Stahl also was an Engineering Technician with the Department.

Just a few days removed from celebrating Women in Construction Week, ACPA extends our heartfelt sympathies to those that had to pleasure to know and to work with Kirsten.   We hold up her memory as inspiration to all young women entering or thinking about pursuing a career in a construction field, including in concrete paving.

Funeral arrangements for Kirsten Stahl are as follows:
