Roads leading into Gaza are being repaired after being hit by bombardments in the past two weeks.
A U.N. official said more than 200 trucks of aid were ready to move from Sinai to Gaza.
During previous conflicts, aid had been delivered to Gaza during humanitarian pauses through the Kerem Shalom crossing, which is controlled by Israel.
But Israel has said it will allow no aid to enter from its territory until Hamas releases the hostages it took during its Oct. 7 attack.
It has said aid can enter through Egypt as long as it does not end up in the hands of Hamas.
Egypt has said it will not accept any mass displacement of Gazans into Sinai, reflecting Arab fears that Palestinians could again flee or be forced from their homes en masse, as they were during the war surrounding Israel’s creation.
Egypt is also concerned by security in northeastern Sinai, where it faced an Islamist insurgency that escalated a decade ago, and by the risk of any spillover from Hamas-controlled Gaza.
