William H. Gray III 30th Street Station Redevelopment
Under constructionTimeline: Began 2024; South Station retail concourse opening late 2026; full redevelopment completion targeted 2028
A $550M, ~500,000-sq-ft renovation of the station itself led by Amtrak with Plenary Infrastructure — restoration of the historic main hall, expanded retail concourse, modernized SEPTA platforms, new elevators at the 31st Street entrance, and a new head house at 30th Street. Phase 1 (31st Street entrance improvements) is complete. This is the first piece of the broader $10B 30th Street Station District Plan, which envisions an entirely new transit-centered neighborhood over the rail yards in the decades ahead.
Impact: Most work happens behind hoarding without major service impact, though there are temporary entrance changes. When the station renovation wraps (full completion targeted 2028, with the new South Station retail concourse opening in late 2026), 30th Street will be one of the most modern intercity stations in the US while preserving its 1933 Neoclassical architecture.

Market Street Bridge Rehabilitation
Under constructionTimeline: Began March 2025; full completion ~2029
A $148.9M PennDOT project to rehabilitate the bridges carrying Market Street over the Amtrak tracks and I-76 beside the station. Construction began in March 2025. To avoid disrupting Philadelphia's summer 2026 Semiquincentennial celebrations, PennDOT deferred the most disruptive phase — which is now imminent: overnight I-76 closures began July 20, 2026, and Market Street fully closes to vehicles for roughly 14 months, from late August 2026 to October 2027. Pedestrians and cyclists keep access across the bridge throughout, though PennDOT is steering foot traffic toward Chestnut and Walnut Streets. Full completion is targeted for around 2029.
Impact: Major traffic changes around the station's Market Street side — expect a full vehicle closure of Market Street at the station from late August 2026 through October 2027. Walking access to the station is preserved: the closure is vehicles only. No rail service impact.

Roof & Skylight Restoration
Recently completedTimeline: Completed 2024
Multi-year project to restore the original copper roof, lighting, and the historic skylights over the main concourse. The restoration revealed original architectural details that had been hidden for decades.
Impact: The main waiting room is dramatically brighter and more striking than it has been in 50+ years. No service impact.

Amtrak Acela Fleet Replacement
Under constructionTimeline: NextGen Acela in service since August 2025; 13 trainsets and 32 weekday trips as of July 2026; full 28-trainset rollout by 2027
Not station-specific, but 30th Street is one of the busiest Acela stops. The new NextGen Acela (Avelia Liberty) trainsets entered revenue service on August 28, 2025, and passed one million customer trips by May 2026. As of July 6, 2026, 13 trainsets are in passenger service, supporting 32 weekday Acela trips (up from 26 before that date). Maintenance-facility upgrades have run behind, and Amtrak's earlier expectation of running up to 24 trainsets during 2026 now looks optimistic; all 28 are still slated to phase in by 2027, gradually replacing the original 2000-era Acela fleet.
Impact: Faster, more comfortable Acela service through 30th Street, with roughly 25% more seats per train.
