Future infrastructure

The projects that change which cities are "close." Each is a reason a commute that is hard today may not be in 2030 — and each is subject to funding and schedule risk.

Del Mar bluffs rail realignment / tunnel (LOSSAN corridor) — would move Coaster/Surfliner tracks off the eroding bluffs. VERIFY: SANDAG planning status.
I-5 North Coast Corridor express lanes, Oceanside → La Jolla — phased through the 2030s. VERIFY.
SANDAG airport transit connection (Downtown ↔ San Diego International). VERIFY.
Purple Line / Central Mobility concepts (South Bay ↔ Kearny Mesa ↔ Sorrento Valley) in the Regional Plan. VERIFY.
