San Diego is set to undergo significant changes at its international airport as preparations for the construction of a new Terminal 1 begin. Starting on September 8, the arrivals roadway connecting Terminals 1 and 2 will close to facilitate construction work at the Phase 1B site. This strategic closure is intended to ensure the safety of construction crews during the initial stages of this major project.
Travelers moving between terminals will be redirected through alternative routes on airport grounds, although pedestrian access between Terminals 1 and 2 will remain available until September 22. Following this date, a new pathway leading to the parking structures will be established, connecting Terminal 2 through a newly constructed tunnel.
To assist passengers with luggage during this transition, a terminal loop shuttle bus will be implemented to facilitate easy access to Terminal 2. The existing Terminal 1 will be permanently closed and demolished on the night of September 22, paving the way for the groundbreaking construction of the new terminal.
The first phase of the new Terminal 1 is designed to enhance gate capacity and provide a more spacious and comfortable environment for travelers. Once completed, the new terminal will showcase various shops and amenities reflective of San Diego’s rich culture. The construction of Phase 1B will occur at the old Terminal 1 site, contributing to the overall modernization effort at the airport.
The San Diego County Regional Airport Authority recently announced these changes, highlighting the scope and impact of the $3.8 billion project, which is expected to generate as many as 20,000 construction-related jobs. The project, initiated in November 2021, is part of a broader modernization initiative that includes substantial infrastructure improvements and better transportation connections to the airport.
This terminal upgrade is one of the most eagerly anticipated public works projects in San Diego over the past few decades. It promises not just to improve the functionality of the airport but also to enhance the overall travel experience for millions of passengers visiting the city each year.
