Im not disagreeing with you about people avoiding the tolls, I just dont believe that number is as high as you may believe. What about population increases contributing to higher traffic numbers? Surrey alone has increased 40,000+ since 2010. Im sure a small number of those people might be going over the bridge once in a while.

Traffic over AFB has been on the rise since the day it opened, not just since the tolls kicked in. Note the GMT is pretty much at capacity and has been for a long time.

First thing, most of Surrey's growth over the past few years has been east of 144 Street. Perfect candidates to take the Port Mann bridge (the reason we upgraded it!). The Western most areas of growth in Surrey are south of 64 Ave. So if those people were taking the AFB, they would be approaching from the South on 91. There hasn't been significant growth in the northern areas that would result in the sudden surge of people taking the AFB from the SFPR in recent years.
The increase in traffic coming from the SFPR doesn't correspond to a decrease in traffic on Nordel. It still backs up past the pedestrian overpass every morning.
It does however correspond to lower numbers going over the PMB in the reverse peak direction, and during most of the day.
Also, it only takes a small amount of excess traffic to cripple a bridge.
When the tolls went in on the PMB, the Pattullo became insane. When I was at a workshop for the New Pattullo, the traffic engineers were fielding a lot of questions, and they bluntly said that because the Pattullo was at capacity already, the increase of drivers avoiding the tolls even if only a few thousand a day, pushed the bridge past the breaking point.
For example, not all increases are equal. If x cars get over the bridge in y minutes, 2x cars does not take 2y time. Under capacity, it will take less than 2y time, over capacity it could take far more than 2y time. They were saying that an increase of just a hundred cars an hour was making people take 20 minutes longer to get over the bridge.
So either those people aren't going to like the changing to the Pattullo and change to the AFB, or people who were taking the Pattullo are going to take the AFB. After a while traffic most days at the Pattullo did get better (better than the worst it got), but traffic at the AFB did get worse.
And all it takes is a few hundred extra cars taking the SFPR to the 91 Connector to the AFB for it to cause insane backups on that road because they merge down to one lane before traffic heading to Nordel can get around people waiting for the AFB. So that just makes the problem worse because there are cars not even going onto the AFB that are in the line for the AFB on the 91 connector.
So the OP basically asked why is traffic so bad to get to the AFB from the SFPR, and I think it is because of people skipping the toll on the PMB. Is every car skipping the toll, of course not. But there are enough of them to cause the congestion on that section of road.
So the OP was asking what can be done? Well, I think the problem would significantly decline if people who should go over the PMB did go over the PMB.
Other than that, the next best thing you could do is widen the Nordel overpass. Right now it is 3 lanes eastbound. And only 1 lane carries traffic from the SFPR. If traffic from the SFPR didn't have to merge down to one lane, then the leftmost lane could be for turns, and all the people caught in the traffic heading to Nordel wouldn't be stuck in that mess making it worse.
