We present a detailed analysis of new ALMA observations of the disk aroundthe T-Tauri star HD 143006, which at 46 mas (7.6 au) resolution reveal newsubstructures in the 1.25 mm continuum emission. The disk resolves into aseries of concentric rings and gaps together with a bright arc exterior to therings that resembles hydrodynamics simulations of a vortex, and a bridge-likefeature connecting the two innermost rings. Although our $^{12}$CO observationsat similar spatial resolution do not show obvious substructure, they reveal aninner disk depleted of CO emission. From the continuum emission and the COvelocity field we find that the innermost ring has a higher inclination thanthe outermost rings and the arc. This is evidence for either a small($\sim8^{\circ}$) or moderate ($\sim41^{\circ}$) misalignment between the innerand outer disk, depending on the specific orientation of the near/far sides ofthe inner/outer disk. We compare the observed substructures in the ALMAobservations with recent scattered light data from VLT/SPHERE of this object.In particular, the location of narrow shadow lanes in the SPHERE image combinedwith pressure scale height estimates, favor a large misalignment of about$41^{\circ}$. We discuss our findings in the context of a dust-trapping vortex,planet-carved gaps, and a misaligned inner disk due to the presence of aninclined companion to HD 143006.
