Southern Haiti has been cut off from the rest of the country after a bridge collapsed due to Hurricane Matthew. In the Dominican Republic the storm has been blamed for at least four deaths.
The Route Nationale 2 highway - to and from La Digue Bridge - is the only one linking the capital Port-au-Prince to the southern peninsula, an area that been hard hit by the deadly storm.
"An emergency meeting is taking place to restore access, but it's going to be difficult to find an alternative route," civil protection spokesman Edgar Celestin told the French news agency AFP, adding that it is impossible to know how many fatalities there are or the extent of damage in southern Haiti, as civil protection workers there could not be reached or get outdoors to assess the situation.
Rising sea levels and torrential rains have caused major flooding in southern Haiti since Sunday evening.
