TL/DR –
The Interstate 10 Deck Park Tunnel in downtown Phoenix has been dedicated to the late civil engineer, Dean Lindsey, who managed its development. As part of the dedication, signs reading “Dean Lindsey Memorial Tunnel” were placed at each tunnel entrance, and a plaque was installed in the park. Lindsey oversaw the development of I-10’s downtown-area segments in the 1970s and ’80s, and was key to the early Valley freeway program; he worked for the Arizona Department of Transportation from 1974 until 2006.
Phoenix Interstate 10 Deck Park Tunnel Dedication Ceremony for Dean Lindsey
The Interstate 10 Deck Park Tunnel in downtown Phoenix was recently dedicated to the late civil engineer, Dean Lindsey, a key figure within Arizona Department of Transportation (ADOT). The ceremony took place at Margaret T. Hance Park, located above the I-10 tunnel, with ADOT officials, former coworkers, and Lindsey’s family present.
As part of the dedication, signs bearing “Dean Lindsey Memorial Tunnel” were installed at each tunnel entrance, and a commemorative plaque was erected in the park. “Dean Lindsey was a unifying force in the design and realization of I-10 and Hance Park over 30 years ago,” shared ADOT Director Jennifer Toth.
Dean Lindsey’s Legacy in Shaping the Interstate 10 Tunnel
Lindsey supervised the construction of I-10’s downtown segments during the 1970s and ’80s, leading up to the Deck Park Tunnel’s public opening in August 1990. The late engineer, who began his tenure at ADOT in 1974, retired in 2006 and passed away in 2023.
Dean’s intense dedication to the Papago Freeway project is highly acknowledged. According to Mickelson, “he often worked seven days a week, showing great interpersonal skills during a politically charged time. He was instrumental in planning and designing for the tunnel project, the I-17 Stack interchange, and the I-10 connections with State Route 51.”
Lindsey’s daughter, Laura Felten, expressed her father’s love for his work at ADOT and the pride he felt looking back at his career. “He often spoke of the accomplishments, camaraderie with coworkers, and problem-solving required to deliver projects,” Felten recalled. “Our family refers to the Deck Park Tunnel as ‘PaPa’s Tunnel.’ We are incredibly honored that it now bears his name.” The naming was approved by the Arizona State Board on Geographic and Historic Names.
