To complement the 2MASS Redshift Survey (2MRS) and the 2MASS Tully-Fishersurvey (2MTF) a search for 21cm HI line emission of 2MASS bright galaxycandidates has been pursued along the dust-obscured plane of the Milky Way withthe 100m Nancay Radio Telescope. For our sample selection we adopted anisophotal extinction-corrected K-band magnitude limit of $K_s^o = 11.25$mag,corresponding to the first 2MRS data release and 2MTF, for which the 2MASXcompleteness level remains fairly constant deep into the Zone of Avoidance(ZoA). About one thousand galaxies without prior redshift measurementaccessible from Nancay (Dec > -40\deg) were observed to an rms noise level of~3 mJy for the velocity range -250 to 10'600 km/s. This resulted in 220 clearand 12 marginal detections of the target sample. Only few detections haveredshifts above 8000 km/s due to recurring radio frequency interference (RFI).A further 29 detections and 6 marginals have their origin in non-targetgalaxies in the telescope beam. The newly detected galaxies are on averageconsiderably more \HI-rich (mostly $10^9 - 10^{10}$M$_\odot$) compared tosystematic (blind) HI surveys. The HI detections reveal various new filamentscrossing the mostly uncharted northern ZoA (e.g. at $\ell \sim 90\deg, 130\deg,160\deg$), whilst consolidating galaxy agglomerations in Monoceros and Puppis($\ell \sim 220\deg, 240\deg$). Considerably new insight has been gained aboutthe extent of the Perseus-Pisces Supercluster through the confirmation of aridge ($\ell \sim 160\deg$) encompassing the 3C129 cluster that linksPerseus-Pisces to Lynx, and the continuation of the second Perseus-Pisces arm($\ell \sim 90\deg$) across the ZoA.
