HANOVER, MD – Governor Larry Hogan today named Holly Arnold Administrator of the Maryland Department of Transportation Maryland Transit Administration (MDOT MTA). Ms. Arnold has been serving as the Acting Administrator since June 7. Prior to her appointment as Acting Administrator, Administrator Arnold had served as Deputy Administrator/Chief Planning, Programming, and Engineering Officer.

“Holly has proven herself to be a champion for transportation projects that have a powerful impact on the people she serves," Governor Hogan said. “Her experience and ability to take on the most complicated challenges and see them through successfully makes her an ideal leader for MDOT MTA."

During her tenure at MDOT MTA, Ms. Arnold has overseen all aspects of the agency's $3 billion six-year capital program; led the development of the Central Maryland Regional Transit Plan; successfully applied for over $80 million in federal grants; spearheaded the agency's asset management program; and oversaw the creation of the agency's Transit Oriented Development guidelines and station area concepts. Her most recent accomplishment in her role as Acting Administrator is the launch of the $43 million Fast Forward initiative, a wide-ranging effort that focuses on improving transit reliability, travel times and customer safety, with the overall goal of enhancing the complete door to door transit experience.

“For the last few months and for years before that, Holly has demonstrated the power of strong leadership and a commitment to innovation that is already helping to put MDOT MTA at the forefront of transit agencies nationwide," said Transportation Secretary Greg Slater. “Her strong skills are the perfect complement for her position as Administrator."

Ms. Arnold was recognized in 2018 as a Top 40 Under 40 Transit Professional by Mass Transit Magazine, and as one of the 40 Under 40 Outstanding Young Leaders honored by the Baltimore Business Journal for her contributions to her organization and her community. She holds an undergraduate degree from Duquesne University and a Master's in Public Administration from the University of Pittsburgh's Graduate School of Public and International Affairs.
