Traffic on New York's Tappan Zee Bridge has come to a standstill after a crane collapsed around midday Tuesday, blocking all lanes.
NBC New York reported that three drivers and two workers were injured, but did not sustain serious injuries.
Governor Andrew Cuomo tweeted Tuesday afternoon that the bridge will not be reopened until a structural inspection is completed in the next several hours.
He also said it wasn't immediately clear why the crane collapsed as it was performing a routine task when it happened. Cuomo said that an investigation is under way.
Photos from the scene show debris scattered across the road.
State police said that barricades will be lifted so that drivers can turnaround and exit the bridge, according to NBC New York. Local authorities tweeted that all lanes remain blocked and that northbound drivers must take exit 8 and southbound drivers must take exit 15.
The accident occurred between milepost 13.1 and 16.2 on I-87, according to the New York Thruway Authority.
Traffic appears to be completely stopped in both directions on Google Maps. New York Thruway Authority traffic cameras in the area are currently unavailable due to the accident.
The next closest Hudson River crossings at the Bear Mountain Bridge and the George Washington Bridge also saw significant delays Tuesday afternoon.
