A fire apparatus includes a chassis, axles coupled to the chassis, a turntable rotatably coupled to the chassis, and an aerial ladder assembly pivotably coupled the turntable and including a ladder section. The ladder section includes a first base rail and a second base rail extending longitudinally, a plurality of ladder rungs extending between the first base rail and the second base rail, a top plate positioned above the first base rail, a series of lacing members coupled to the top plate and the first base rail, and a gusset plate coupled to the top plate and at least one of the lacing members. The top plate extends at least one of (a) laterally inward of the gusset plate and (b) laterally outward of the gusset plate. The top plate has a solid cross section.
