NEW YORK (CBSNewYork) — Falling ice caused some problems for PATH train riders at the World Trade Center station Friday morning.

The main exit at the station was closed shortly before 9 a.m. because of falling ice, forcing commuters to walk underground to 200 Vesey Street in order to exit, CBS 2 learned.

Commuters on social media described walking underground for at least 30 minutes to get out.

The incident also suspended service from the World Trade Center to Newark and Hoboken.

The station was reopened and service was restored around 9:30 a.m.

The Exchange Place station was also briefly closed Friday morning because of falling ice.
