  We present the visual orbit of the double-lined spectroscopic binary HD
224355 from interferometric observations with the CHARA Array, as well as an
updated spectroscopic analysis using echelle spectra from the Apache Point
Observatory 3.5m telescope. By combining the visual and spectroscopic orbital
solutions, we find the binary components to have masses of M1 = 1.626 +/- 0.005
Msun and M2 = 1.608 +/- 0.005 Msun, and a distance of d = 63.98 +/- 0.26 pc.
Using the distance and the component angular diameters found by fitting
spectrophotometry from the literature to spectral energy distribution models,
we estimate the stellar radii to be R1 = 2.65 +/- 0.21 Rsun and R2 = 2.47 +/-
0.23 Rsun. We then compare these observed fundamental parameters to the
predictions of stellar evolution models, finding that both components are
evolved towards the end of the main sequence with an estimated age of 1.9 Gyr.
