  The Milky Way is a barred spiral galaxy with "bar lanes" that bring gas
towards the Galactic Center. Gas flowing along these bar lanes often
overshoots, and instead of accreting onto the Central Molecular Zone, it
collides with the bar lane on the opposite side of the Galaxy. We observed G5,
a cloud which we believe is the site of one such collision, near the Galactic
Center at (l,b) = (+5.4, -0.4) with the ALMA/ACA. We took measurements of the
spectral lines $^{12}$CO J=2-1, $^{13}$CO J=2-1, C$^{18}$O J=2-1, H$_2$CO
J=3$_{03}$-2$_{02}$, H$_{2}$CO J=3$_{22}$-2$_{21}$, CH$_{3}$OH
J=4$_{22}$-3$_{12}$, OCS J=18-17 and SiO J=5-4. We observed a velocity bridge
between two clouds at $\sim$50 km/s and $\sim$150 km/sin our position-velocity
diagram, which is direct evidence of a cloud-cloud collision. We measured an
average gas temperature of $\sim$60 K in G5 using H$_2$CO integrated intensity
line ratios. We observed that the $^{12}$C/$^{13}$C ratio in G5 is consistent
with optically thin, or at most marginally optically thick $^{12}$CO. We
measured 1.5 x 10$^{19}$ cm$^{-2}$(K km/s)$^{-1}$ for the local X$_{CO}$,
10-20x less than the average Galactic value. G5 is strong direct observational
evidence of gas overshooting the Central Molecular Zone (CMZ) and colliding
with a bar lane on the opposite side of the Galactic center.
