I-37 provides an important connection between I-35 and the Texas Gulf Coast and it is one of the few limited-access hurricane evacuation routes away from the southern Texas coast. In the 1960s, constuction of I-37 began in the urban areas of Corpus Christi and San Antonio and the segments in rural areas were completed by the 1980s. Growth along the I-37 corridor in recent years have been associated with various issues, including the lack of frontage roads, mobility and operational issues and heavy truck activities. To begin identifying solutions to these issues, TxDOT initiated a corridor study to investigate existing and future conditions and needs along the I-37 corridor.
TxDOT is conducting the I-37 Corridor Study along I-37 from the interchange of I-410 south of San Antonio to I-69E in Corpus Christi, a distance of approximately 119 miles. The study area includes the immediate area along the corridor including Bexar, Atascosa, Live Oak, San Patricio and Nueces counties, and the cities of San Antonio and Corpus Christi. The purpose of this study is to establish performance measures to determine how well the corridor is performing in areas such as safety, pavement, bridges, mobility and freight movement and then to develop improvement programs for the I-37 corridor.
Public involvement opportunities will be provided throughout the study process. The project team will seek input from stakeholders who live and work along the corridor, and who have a particular interest in its improvement. All of the comments received from stakeholders will be considered by the project team as they conduct their performance-based analysis of the I-37 corridor.
The I-37 corridor study began in the summer of 2016 and will conclude by the fall of 2017.
