In my earlier answer I used an Atlas Warren truss bridge (150-883). With a piece of scribed balsa laid in to look like planking, it would work well as a single lane auto bridge as David suggested.
I've seen flat cars and plate girder bridges used as bridges for driveways and farm field access.
Have fun,

hbgatsfI want to install a truss bridge for HO scale vehicles (cars and trucks.) Can I use a N scale train bridge for this application?
This presumes the trusses aren't "bonded" with girders across the top. Look at earlier truss bridge pictures to see the methods used to minimize material cost 'back in the day' -- you might use stanped crossbeams and guy 'cable' ties across the top instead of a full structural truss arrangement up there. There were some interesting examples in the history of New Haven Shore Line bridges over the years...
Put up stop signs. Single lane bridge. Good for rural road.
Too small. I just put two CMW pickups side by side in an HO bridge. can barely pass. Maybe a double track N bridge.
Good luck,
