TFA suggests it's not split up:
> Intel will put a 916,000-pound "super load" on the road in Ohio on Wednesday, for a trip that will cover approximately 150 miles in nine days and snarl traffic for over a week...
> Four of these loads, including the one hitting the road now, weigh around 900,000 pounds — that's 400 metric tons, or 76 elephants.
> Intel's 916,000-pound shipment is a "cold box,"...
EDIT: Further information in the ODOT advisory detailing the schedule of this one shipment confirms 916k pounds is not split among multiple loads:

> This is the twelfth of nearly two dozen "super loads"... This load... measures approximately 23’ tall, 20’ wide, 280’ long, and weighs 916,000 pounds.
