  We obtain a dynamical formulation of two-dimensional gravity from a
non-Einsteinian phase in higher dimensions $(D=3+2n)$. The formalism is
associated with (at least) one extra dimension of vanishing proper length, thus
being inequivalent to either a Kaluza-Klein compactification or the Mann-Ross
dimensional reduction defined upon a singular limit. The emergent solutions
admit any arbitrary curvature in contrast with Jackiw-Teitelboim constant
curvature gravity. We present the static and homogeneous solutions as explicit
examples. The effective field equations are shown to remain unaffected by the
inclusion of higher Lovelock terms beyond Einstein.
