  We present the first results of a high-resolution Karl G. Jansky Very Large
Array (VLA) imaging survey of luminous and ultra-luminous infrared galaxies
(U/LIRGs) in the Great Observatories All-Sky LIRG Survey (GOALS). From the full
sample of 68 galaxies, we have selected 25 LIRGs that show resolved extended
emission at sufficient sensitivity to image individual regions of
star-formation activity beyond the nucleus.~With wideband radio continuum
observations, which sample the frequency range from $3-33$ GHz, we have made
extinction-free measurements of the luminosities and spectral indicies for a
total of 48 individual star-forming regions identified as having de-projected
galactocentric radii ($r_{G}$) that lie outside the 13.2$\mu$m core of the
galaxy.~The median $3-33$ GHz spectral index and 33 GHz thermal fraction
measured for these "extranuclear" regions is $-0.51 \pm 0.13$ and $65 \pm 11\%$
respectively.~These values are consistent with measurements made on matched
spatial scales in normal star-forming galaxies, and suggests that these regions
are more heavily-dominated by thermal free-free emission relative to the
centers of local ULIRGs.~Further, we find that the median star-formation rate
derived for these regions is $\sim 1 M_{\odot}$ yr$^{-1}$, and when we place
them on the sub-galactic star-forming main sequence of galaxies (SFMS), we find
they are offset from their host galaxies' globally-averaged specific
star-formation rates (sSFRs).~We conclude that while nuclear starburst activity
drives LIRGs above the SFMS, extranuclear star-formation still proceeds in a
more extreme fashion relative to what is seen in local spiral galaxies.
