I drove to San Carlos this weekend. The last two toll stations on Hwy 15 have signs posted that they only accept pesos, no US dollars. I went through on Thrusday and they were enforcing this, but another member of our group came down on Saturday used US dollars with no problems. As is typical in Mexico, the rules seem to be selectively enforced.
When I went through they were making people get out of line and stop at the small store next to the toll booth to get money exchanged, then get back in line.
The Magdalena toll was 17 pesos, the Hermosillo toll was 53 pesos. Have the pesos available before you get there in case they won't take US dollars.
