Our Subaru-based weak-lensing analysis detects three mass clumps forming an ~4Mpc filamentary structure elongated in a north-south orientation. The northern (M_200_=2.61_-0.60_^+0.51^x10^14^M_{sun}_) and middle (M_200_=1.09_-0.43_^+0.34^x10^14^M_{sun}_) mass clumps separated by ~1.3Mpc are associated with A1240 and colocated with the X-ray peaks and cluster galaxy overdensities revealed by Chandra and MMT/Hectospec observations, respectively. The southern mass clump (M_200_=1.78_-0.55_^+0.44^x10^14^M_{sun}_), ~1.5Mpc to the south of the middle clump, coincides with the galaxy overdensity in A1237, the A1240 companion cluster at z=0.194. Considering the positions, orientations, and polarization fractions of the double radio relics measured by the LOFAR study, we suggest that A1240 is a postmerger binary system in the returning phase with a time since collision of ~1.7Gyr. With the SDSS DR16 data analysis, we also find that A1240 is embedded in the much larger scale (~80Mpc) filamentary structure whose orientation is in remarkable agreement with the hypothesized merger axis of A1240.2022ApJ...925...68Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/925/68CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/4 : Abell and Zwicky Clusters of Galaxies (Abell+ 1974)VII/110 : Rich Clusters of Galaxies (Abell+ 1989)V/154 : Sloan Digital Sky Surveys (SDSS), Release 16 (DR16) (Ahumada+, 2020)J/AJ/112/36 : Velocities in Abell 3266 (Quintana+ 1996)J/ApJ/519/533 : ROSAT observations of ACO clusters (David+, 1999)J/ApJS/150/1 : VV29 and NGC 4676 HST photometry (Benitez+, 2004)J/AJ/132/926 : Galaxies in the Hubble Ultra Deep Field (Coe+, 2006)J/ApJ/660/239 : MaxBCG catalog of galaxy clusters from SDSS (Koester+, 2007)J/A+A/503/357 : Redhift catalog of A1237+A1240 galaxies (Barrena+, 2009)J/ApJS/191/254 : GMBCG galaxy cluster catalog from SDSS DR7 (Hao+, 2010)J/A+A/540/A43 : New redshifts for Abell 1758N galaxies (Boschin+, 2012)J/ApJS/199/34 : Clusters of galaxies in SDSS-III (Wen+, 2012)J/ApJ/772/131 : Musket Ball Cluster redshift catalog (Dawson, 2013)J/ApJ/805/143 : MC2: redshift analysis of CIZA J2242.8+5301 (Dawson+, 2015)J/A+A/581/A14 : Updated Planck catalogue PSZ1 (Planck+, 2015)J/AJ/150/31 : Phot. and redshifts of galaxies in the UDF (Rafelski+, 2015)J/MNRAS/450/3665 : CoMaLit.
