The invention discloses a transition duct assembly. According to the invention, a turbomachine (10) includes a plurality of transition ducts (50) disposed in a generally annular array and including a first transition duct (130) and a second transition duct (132). Each of the plurality of transition ducts (50) includes an inlet (52), an outlet (54), and a passage (56) extending between the inlet (52, 162) and the outlet (54, 164) and defining a longitudinal axis (90), a radial axis (94), and a tangential axis (92), the outlet (54) of each of the plurality of transition ducts (50) offset from the inlet (52) along the longitudinal axis (90) and the tangential axis (92). The turbomachine further includes a support ring assembly downstream of the plurality of transition ducts (50) along a hot gas path (104), and a plurality of mechanical fasteners (200) connecting at least one transition duct (50) of the plurality of transition ducts (50) to the support ring assembly.
