Hudson Tunnel funding deadline: schedule and risk takeaways for project teams

30 Second Briefing
Federal funding for New York’s US$16bn Hudson Tunnel Project has been frozen, forcing the Gateway Development Commission to suspend works from 6 February after spending over US$1bn and employing about 1,000 site workers. A Manhattan federal judge has issued a temporary restraining order, giving the administration until 5 p.m. on 12 February to restore reimbursements or appeal, while contractors warn that demobilisation, resequencing and remobilisation will add cost and delay. Sites are now in “safe-pause” mode, with dewatering, ground support and environmental monitoring maintained, and assembly of two Herrenknecht TBMs in New Jersey likely to slip beyond the planned spring 2026 launch without funding certainty.
Technical Brief
- Around 1,000 tunnel and rail construction workers now face layoff as major packages are mothballed.
- Contractors warn demobilisation and later remobilisation will require resequencing of tunnelling and rail interface works.
- Safe-pause activities include stabilising open excavations, securing partially built structures and maintaining environmental monitoring systems.
- Dewatering and ground support operations continue to prevent deterioration of excavations and previously completed underground works.
- Two Herrenknecht TBMs, factory-tested and shipped to New Jersey, remain unassembled pending funding clarity.
- Episode underlines how funding interruptions can rapidly convert active megaprojects into asset-protection and safety-maintenance mode.
Our Take
At a projected US$16 billion, the Hudson Tunnel Project sits at the very top end of cost among the 684 Infrastructure stories in our database, which means any delay or deferral in federal backing tends to crowd out smaller transit schemes in New York and New Jersey funding pipelines.
Herrenknecht’s track record with TBMs up to 19 m diameter signals that the Gateway Program can draw on equipment proven in complex urban and soft-ground conditions, reducing technical risk relative to less experienced suppliers but increasing pressure on interface management and logistics in Manhattan.
With US$1 billion already spent ahead of the spring 2026 horizon, the Gateway Development Commission is effectively in a sunk-cost position where a negative funding decision would likely trigger expensive demobilisation and claims—an outcome rarely seen in our infrastructure coverage at this scale.
