$1.4B Loop 1604 Expansion Moves Through Further Interchange Work
Weekend traffic arrangements will support continuing work within the major San Antonio highway program.
San Antonio’s Loop 1604 North Expansion is moving through another stage of construction, with additional closures scheduled around the I-10 interchange from Friday evening through Monday morning.
The work forms part of the approximately $1.4 billion program to expand roughly 23 miles of highway from four lanes to ten.
Reconstruction of the I-10 interchange is one of the program’s largest components, carrying an approximate value of $463 million. The interchange work sits within a broader effort to increase capacity and rebuild connections along the northern corridor.
The latest October 30 notice concerns traffic arrangements required to continue active works. It provides a construction scheduling update within an established program.
The overall completion target remains 2028 in the supplied project information. A contractor for the specific weekend work package was not identified.
The scale of the program means construction is progressing through multiple work areas and traffic stages, with temporary closures supporting the continuing transformation of the corridor.
