It used to be only from 10am-8pm, but they lifted that restriction recently. Now you can drive on the shoulder on those two days.
I did that last time I went to Vegas, as they made special allowance for it on January 2, due to the New Years holiday. Most people were afraid to do it, as it felt unnatural.
I don't think this will do a lot of good during heavy traffic times, because the backup is due to the necessity to slow down for the (almost always closed) fruit inspection station at the border. and not as much because of a lack of lanes going south.
