Loop 1604 North Expansion Status, Cost & Completion Date (2026 Guide)
The Loop 1604 North Expansion is a major infrastructure project expanding 23 mi of San Antonio's northern corridor from SH 16 to I-35 under the official loop 1604 north expansion program. Managed by TxDOT, this $1.4B urban highway upgrade replaces a congested four-lane roadway with a modern ten-lane expressway featuring expanded frontage roads and multi-use paths. Funded through TxDOT State and Federal Transportation Improvement Programs, the expansion addresses heavy freight and commuter traffic across Bexar County's fastest-growing commercial districts. The official plans and route map outline an alignment built in five distinct construction segments to minimize traffic disruption while right-of-way acquisition and utility relocations proceed. Following extensive environmental review processes, the project enhances regional connectivity near I-10 and US 281. Construction activities remain actively underway, with full completion date milestones targeted for 2028, significantly reducing travel times across Northern San Antonio.
Project information is compiled from official agency documents, federal records, environmental reviews, and verified public announcements.
