$3 and a monthly hangtag contract of $40. The Burnett Transit Center was designed to have a park and ride facility next to the Casa de Amigos Health Center; it was scheduled to open in late 2014, but the project was canceled in 2011 and scaled back to a multimodal stop. For the original 2004 portion of the Red Line, the architectural firm Pierce Goodwin Alexander & Linville, of Houston, was in charge of the final architectural/engineering design and design support, with a $2.3 million contract. However, all stations south of Burnett Transit Center were designed by the Houston office of St. Louis-based architectural firm Hellmuth, Obata & Kassabaum. All stations are of similar design— long and partially covered by glass roofs. Station length was constrained by the distance between crosswalks in downtown city blocks; station platforms are low-floor and high. The line includes a bridge along Main Street which separates the double-track main line and a third pocket track from UP's line and three streets. A yard and a maintenance facility for the Red Line is connected by loop track to the south of the Fannin South station. The right-of-way and the stations for the original 2004 line were built by three contractors for approximately $115 million: Texas Sterling Construction Co. of Houston, Bencon Management of Houston and Beers Construction Co. of Atlanta. The line construction was divided into five sections, with a resident engineer for each section, to speed up construction. Purple (Southeast) and Green (East End) Lines The , 10-station Purple Line, and seven stations of the , 9-station Green Line opened on May 23, 2015. The final two stations of the Green Line opened on January 11, 2017. A storage yard/inspection facility is located off of Harrisburg and Clifton.
