AM bridge problems

Are there any reference materials for the AM breadth module of the exam? I notice on the ncees site there are reference materials on other tests but nothing for structural? My experience is in buildings so I am wondering if I need to buy the Aashto manual as it’s not cheap and I don’t plan to ever use it in my career. Or will portions of that Manual be made available? Does anyone have any advice on what tables I should find and print from the internet to use so that I could avoid buying the manual. Or recommendations on resources to use to study for the bridge questions 
Thanks 

You will want at least Chapters 1-6 of AASHTO, but all are recommended.  David Connor has some bridge books that are helpful.  Bridge is 10 or so morning problems, so you will want to be prepared for them. 

Thanks for the info
