Houston’s Metropolitan Transit Authority of Harris County provided an estimated 148,000 light rail rides to NCAA Final Four college basketball games at Reliant Stadium and related events at other venues during four days. METRORail reported the highest Saturday and Monday total since entering service in 2004, providing more than 93,000 rides on each of the two game days. Hundreds of volunteer ambassadors positioned along the Red Line greeted visitors and helped them navigate the experience.
