Mario G. Medina, P.E., is the district engineer for TxDOT's San Antonio District.

The district includes 12 counties: Atascosa, Bandera, Bexar, Comal, Frio, Guadalupe, Kendall, Kerr, McMullen, Medina, Uvalde and Wilson.

A 23-year TxDOT veteran, Medina brings a wealth of knowledge about freight and multi-modal operations to the San Antonio position. This knowledge will work well in helping San Antonio meet its unique mobility challenges.

Since April 2006, Medina has been District Engineer in Laredo. He has directed all transportation and multimodal/intermodal planning projects in the eight-county district. During his tenure, the Laredo district inaugurated the FM 1472 Railroad Grade Separation and US 83-SH 359 Interchange. Also, Medina has been instrumental in bringing to fruition the Laredo Cuatro Vientos project, set for letting in early 2009, and the Del Rio Outer Loop pass-through financing project with Val Verde County.

Medina began his TxDOT career in the Laredo area office where he worked for five summers while pursuing his degree. His first full-time position was in field coordination in the Design Division. From there, he moved up the ranks until he left the division in 2002 as a manager of the Consultant Contract office.

He then joined the Transportation Planning and Programming Division as multimodal section director, where he was responsible for various multimodal issues including railroad planning, railroad safety inspections, state sponsorship of the Gulf Intercoastal Waterway, pedestrian and bicycle planning and multimodal/intermodal planning projects.

Medina earned a Bachelor of Science degree in civil engineering from the University of Texas at Austin in 1986. A native of Laredo, Mario and his wife Janet have three children, Gray, Derek, and Marisa.
