Major Changes Coming to San Diego International Airport with Closure of Terminal 1 on September 22
San Diego, CA — Travelers and drivers heading to San Diego International Airport will experience significant changes starting mid-September, as the airport prepares to close Terminal 1 permanently and undertake a major expansion project. These updates are part of a comprehensive modernization effort to enhance passenger experience, increase capacity, and improve transportation infrastructure.
Road Closures and Traffic Changes Begin September 8
Beginning September 8, the arrivals roadway connecting Terminals 1 and 2 will close for construction. This closure is essential to ensure safe access for crews working on the Phase 1B site of the new Terminal 1 project. During this period, vehicles traveling between the two terminals will be redirected to alternative routes within the airport grounds. These detours are designed to maintain traffic flow and safety during the construction phase.
Despite the roadway closure, pedestrian access between Terminals 1 and 2 will remain open until September 22, allowing travelers to move between terminals on foot without disruptions. However, after September 22, a new pedestrian pathway will be constructed to connect Terminal 2 directly to parking structures via a tunnel, streamlining access for passengers.
Permanent Terminal 1 Closure Scheduled for September 22
On the night of September 22, the existing Terminal 1 will be permanently closed and demolished. This marks a pivotal milestone in the airport’s modernization project, which aims to replace aging facilities with more modern, efficient structures. Following the closure, construction will focus on the development of the new Terminal 1, which is designed to accommodate increasing passenger volumes and provide a more spacious environment.
Details of the New Terminal 1
The first phase of the new Terminal 1 anticipates increased gate capacity and improved amenities. The new facility will feature a variety of shops, restaurants, and cultural displays that reflect San Diego’s local character. Additionally, travelers can expect upgraded infrastructure, enhanced security areas, and better passenger flow to streamline airport operations.
Construction Progress and Project Scope
Initiated in November 2021, the $3.8 billion modernization project is one of the most ambitious public works endeavors in San Diego in recent decades. It includes not only the construction of the new Terminal 1 but also extensive infrastructure improvements across the airport, such as updated transportation links and parking facilities.
This project is expected to generate approximately 20,000 construction-related jobs, providing a significant boost to the local economy and supporting San Diego’s long-term growth plans.
Construction activities at the site of the old Terminal 1 will continue through Phase 1B, culminating in the completion of the new terminal structure. The project aims to ensure that San Diego International Airport remains a modern, competitive transportation hub for the region.
Impact on Travelers and Transportation
During the transition, a terminal loop shuttle bus will operate to assist passengers, especially those with luggage, in reaching Terminal 2 easily. This service is designed to minimize inconvenience as the airport adjusts to the new layout and construction phases.
The changes reflect a strategic effort to modernize San Diego International Airport, enhancing passenger comfort and operational efficiency for years to come. Travelers are advised to stay informed about the upcoming closures and alternative routes during this period.
Conclusion
As San Diego International Airport advances its redevelopment plan, the closure of Terminal 1 and associated road adjustments mark a significant milestone. When completed, the expanded and modernized Terminal 1 will significantly improve the airport experience and support San Diego’s growth as a major travel destination and transportation hub.
