So going to the gym this AM, there was a bit over a 4km backup from the Hola! market to the peaje on the eastbound autopista de las americas. This was around 845AM that I witnessed it. On the way back, a bit after 1PM, it had calmed down to maybe 15 or 20 cars deep. It appears to me that the reason is that they are making about 1/2 of the peaje exclusively for paso rapido. I'm guessing that they're trying to create incentives for folks to get the paso rapido. It's going to be very painful to get there.
