The Bog Walk Gorge in St. Catherine is impassable due to flooding.
The National Works Agency (NWA) says motorists should use alternative routes through Sligoville, and Barry in St. Catherine.
NWA Communication Manager Stephen Shaw said a section of Marcus Garvey Drive is also flooded.
In addition, there are reports of a landslide affecting Wilmington Road in St. Thomas.
Mr. Shaw said roadways in Trelawny, Westmoreland and Clarendon are also affected by landslides and flooding.
He noted that northern parts of Clarendon are currently most affected by flooding but the NWA is now monitoring the southern end of the parish, since it tends to be affected by flood waters coming from the north.
Sections of Clarendon which are inundated by flood waters include Aenon Town, the Trout Hall main road, Denbigh to Manchester Avenue main road and adjoining streets.
The National Works Agency is especially advising caution in Aenon Town near the Thatch Walk bridge due rising water levels affecting the roadway.
Radio Jamaica News was also informed that the Pennants main road is blocked by fallen trees.
Member of Parliament for North Central Clarendon, Robert Morgan, also shared information on flooding in the Bucknor area.
He said the road in Suttons has been split in two, making it impassable, and the Morgan's Pass to Colonel's Ridge road "pretty much doesn't exist anymore" due to a significant number of landslides. The road, which he said is the main connector between Chapelton and Kellits, can no longer be traversed by vehicles.
Mr. Morgan also reported landslides, breakaways and fallen trees in Beckford Crawl.
He said further assessment will have to be done to determine the full extent of damage to the roads.
More damage to come?
The NWA has said, as the rains persist, it is expecting more reports of blocked or damaged roads.
NWA Communication Manager Stephen Shaw warned that the continuous rain over an extended period will lead to rockfalls, breakaways, and landslides, especially in areas susceptible to these occurrences.
He said the NWA is monitoring both East Rural St. Andrew and West Rural St. Andrew, which are prone to these kinds of incidents.
Mr. Shaw urged the public to exercise "extreme caution" as heavy rain continues across sections of the country.
