Early life and education
Early life and education
Rosales was born in Guatemala City, Guatemala, in 1961, the eldest of four sons of Marco Antonio Rosales, a pharmacist, and Lidia Izás, a homemaker. He earned a degree in architecture at the Universidad Francisco Marroquín in 1984. In 1985 he enrolled at the Massachusetts Institute of Technology (MIT) to study Urban and Environmental Design, completing a Master of Science in Architecture Studies (SMArchS) degree in 1987. While at MIT, Rosales specialized in urban design and planning, elements that later informed his work in bridge design and aesthetics.
Career
Career
Rosales initially worked with Swiss engineer and bridge designer Christian Menn, and from 1988 to 1996, Rosales served as the lead architect and urban designer for the Leonard P. Zakim Bunker Hill Memorial Bridge over the Charles River. This structure is part of the Central Artery/Tunnel Project, informally called "The Big Dig". During his tenure at this project, he mainly focused in improving the appearance of the highways and bridges as part of the project that helped transform downtown Boston by removing an elevated highway and by opening access to the harbor. In 1997, he started his own independent architecture and engineering professional practice, Rosales + Partners, in Boston. He was involved in the design of three bridge projects: Liberty Bridge at Falls Park on the Reedy in Greenville, South Carolina, completed in 2004, Puente Centenario, over the Panama Canal, Panama, completed in 2004 and Woodrow Wilson Memorial Bridge over the Potomac River in Washington DC, completed in 2008. This latter bridge was granted the Gustav Lindenthal award. Other projects include the Phyllis J. Tilley Memorial Bridge over the Trinity River in Fort Worth, Texas, completed in 2012, the Christina and John Markey Memorial Pedestrian Bridge, completed in 2013, the Moody Pedestrian Bridge, completed in 2016 in Austin, Texas, the Frances Appleton Pedestrian Bridge and Longfellow Bridge restoration completed in 2018 in Boston, Massachusetts. In 2001 he instituted the Miguel Rosales Award for the Universidad Francisco Marroquín School of Architecture student with the highest grade point average in his class.

Design philosophy
Rosales’s design philosophy centers on creating cost-effective, architecturally distinctive, and visually engaging structures that contribute to their surroundings. He combines architectural considerations with engineering innovation to realize designs that are both functional and compatible with their context. Born in Guatemala, a country where the general public can not express their opinion about urban projects, when he went to live and work in Boston he realized the importance of prioritizing user experience, with an emphasis on designs that accommodate pedestrians and cyclists and incorporate public spaces when appropriate. Some projects met initial resistance from local residents, such as the Fore River Bridge. Rosales emphasized that the conceived vertical-lift bridge had technical advantages, and that a huge effort had been made to avoid immense costs and to improve the appearance. It incorporated elements of the 1936 Art Deco-style bridge, including also features like colored lighting at night and stainless steel screening of the towers at either end to make it more attractive. Rosales' work is raising awareness in communities about the importance of preserving their historic architecture, which continue to inspire great admiration and civic pride.
