We present mosaic images of the Small Magellanic Cloud (SMC) observed with the Spitzer IRAC 3.6 µm and 4.5 µm bands, over two epochs, 2017 August 25-2017 September 13, and 2017 November 24-2018 February 12. The survey region comprises ~30 square degrees covering the SMC and the Bridge to the Large Magellanic Cloud. The region is covered by 52 ~1.1x1.1 degree tiles, with each tile including images in each band for both separate and combined epochs. The mosaics are made in individual tangent projections in J2000 coordinates. The angular pixel size is 0.6" with a resolution of ~2.0". We describe processing to correct or mitigate residual artifacts and remove background discontinuities. The mosaic images are publically available at the Infrared Science Archive.
