This download page includes three options to download contours: (1) by large contour block in geodatabase format, by (2) by sub-block in geodatabase format, or by (3) sub-block in shapefile format.  If you do not use GIS, consider downloading the shapefile format which can be imported into most software programs (e.g. AutoCAD).

The contours are also available for download on the CT ECO download tool.
