Have a look around page 18. Time with congestion was reduced by about 2 hours daily from before the project to after the project. There's also several charts of trip times in there, although some of them are comparing different times of the year which is less apples to apples IMHO. If exhibit 4-133 from the report after the slides is a good comparison, the congestion was effectively eliminated; however the before is during construction, and it's a single day, so that's a bit hard to take at face value; I'm guessing they didn't have any/enough saturday data from the 2009 before construction data set to compare with.
