An archival search for the Alamo-Concepción Aqueduct
In June 1994, the Center for Archaeological Research of The University of Texas at San Antonio undertook an archival search for the San Antonio Water System to evaluate the impact of construction along South Alamo Street in downtown San Antonio. Previous research indicated the probable remains of a stone aqueduct below the street surface near the intersection of South Alamo and South St. Mary's streets. The results of this study indicate that the historical structure may be imperiled by the construction; therefore, monitoring should be conducted during any excavation in that area. If any traces of the aqueduct are encountered, extensive archaeological investigation may be necessary.
