A $\text{K}$-theoretic classification is given of the simple inductive limits of finite direct sums of the type I ${{C}^{*}}$-algebras known as splitting interval algebras with dimension drops. (These are the subhomogeneous ${{C}^{*}}$-algebras, each having spectrum a finite union of points and an open interval, and torsion ${{K}_{1}}$-group.)
