River fishing for bass and walleye ? ? ?

I might be going fishing on wednesday at a near by river, were going to be fishing off an old rail road bridge (now it's a bike trail)and i know there is walleye and small mouth bass in there but what bait/lure do i use for them ?

walleye idk
smallmouth-
i use lures that resemble crayfish so like reds n browns should be fine. and also with a smallmouth dont use too big lures like for largies, smallies have smaller mouths so they eat smaller things (lol) so i guess just downsize a little for smallies
and fish the pilars of that bridge, im pretty sure it would old a fair amount of fish at it!

Thanks for the tips ,i will post back on how well it worked on wednesday (if it does not rain )

use crappie jigs.

@topwaterpro1 will do thanks guys for all the tips !
