The RM75mil Marudi Bridge project being carried out across the Baram River is among them.
They were halted on Wednesday as the floodwaters swelled to dangerous levels, posing a danger to workers.
Sarawak Disaster Relief Management Committee announced the temporary halt.
“Construction works for the Marudi Riverfront, Marudi town square and Marudi bridge projects are affected,” said committee secretary Major Ismail Mahedin.
The riverfront and town square projects cost about RM20mil.
During this monsoon season, emergency food aid is being deployed to rural folk in flood-hit interior Sarawak.
At least 24 villages and schools in rural Marudi and Telang Usan districts in northern Sarawak are in need of food.
Ismail said rescue boats, express boats and heavy duty trucks were being dispatched to facilitate food aid transportation.
The main coordinating agencies involved in food relief operations are Welfare Department, Sarawak Fire and Rescue Department and Civil Defence Unit.
In Marudi district, there are at least 18 settlements and schools in need of food aid.
Among the populated villages are those located in Kuala Tutoh and Lubok Nibong as well as longhouses like Rumah Asing and Rumah Lujang.
Further north in the Telang Usan district, at least six remote longhouses are in need of food.
Among them are Long Ajoi and Long Sepiling which are populated by the Penans.
Sarawak Fire and Rescue Department said big rescue boats had been sent from Miri city to help deliver the food aid to Marudi and Telang Usan.
The Civil Defence Unit is also involved in transporting food aid.
They have sent out dozens of trucks and personnel to help in the delivery process.
Sarawak is in the midst of the landas season, which is the equivalent of the monsoon in the east coast states.
