The San Diego County Regional Airport Authority (Airport Authority) is preparing for construction of the second phase (Phase 1B) of the new Terminal 1 (New T1) at San Diego International Airport (SAN).
Beginning September 8, the arrivals roadway connecting Terminals 1 and 2 will close to allow safe access for construction crews to the Phase 1B construction site. Vehicles traveling between the two terminals will be redirected to alternate on-airport routes. Detailed maps of detour routes are available here. An animated detour map is here.
Pedestrians traveling on foot may use the existing outdoor walkway that connects Terminals 1 and 2 through September 22 to travel between the terminals. Pedestrians can also use the free Terminal Loop Shuttle, which operates daily between 6 a.m. to 11 p.m. Pick up locations are available here.
On the night of September 22, once the final flights have departed, the existing Terminal 1 will permanently close and be demolished.
Phase 1B will be constructed on the site of existing Terminal 1. It will complete construction of the New T1, adding 11 more gates, more passenger amenities including customer lounges, and major infrastructure upgrades.
