Abstract:

This project is part of the broader San Antonio Channel Improvement Project. The latter is a flood control project for the upper San Antonio River and four tributaries -- Martinez, Alazan, Apache, and San Pedro Creeks. The subject of this report is a tunnel and shafts constructed to control flooding on the San Antonio River. The San Pedro Creek Tunnel was the subject of a previous report. San Antonio River Tunnel is the longer of the two inverted siphon tunnels which have been designed to prevent flooding in downtown San Antonio, Texas. Both tunnels are of the same design and same general dimensions, and have excavated by the same tunnel boring machine TBM. Each tunnel will divert floodwater form its respective drainage into an inlet shaft located upstream from the city, and transfer the water beneath the city to an outlet shaft downstream. San Pedro Creek Tunnel extends 5,985 feet form the center of the inlet shaft to the center of the outlet shaft. The San Antonio River Tunnel extends 1,625 feet between the centers of its inlet and outlet shafts.
