We present polarization observations of two Galactic plane fields centered onGalactic coordinates (l,b)=(0 deg,0 deg) and (329 deg, 0 deg) at Q- (43 GHz)and W-band (95 GHz), covering between 301 and 539 square degrees depending onfrequency and field. These measurements were made with the QUIET instrumentbetween 2008 October and 2010 December, and include a total of 1263 hours ofobservations. The resulting maps represent the deepest large-area Galacticpolarization observations published to date at the relevant frequencies withinstrumental rms noise varying between 1.8 and 2.8 uK deg, 2.3-6 times deeperthan corresponding WMAP and Planck maps. The angular resolution is 27.3' and12.8' FWHM at Q- and W-band, respectively. We find excellent agreement betweenthe QUIET and WMAP maps over the entire fields, and no compelling evidence forsignificant residual instrumental systematic errors in either experiment,whereas the Planck 44 GHz map deviates from these in a manner consistent withreported systematic uncertainties for this channel. We combine QUIET and WMAPdata to compute inverse-variance-weighted average maps, effectively retainingsmall angular scales from QUIET and large angular scales from WMAP. From thesecombined maps, we derive constraints on several important astrophysicalquantities, including a robust detection of polarized synchrotron spectralindex steepening of ~0.2 off the plane, as well as the Faraday rotation measuretoward the Galactic center (RM=-4000 +/- 200 rad m^-2), all of which areconsistent with previously published results. Both the raw QUIET and theco-added QUIET+WMAP maps are made publicly available together with allnecessary ancillary information.
