Chart Or Publication
It was snowing sideways on an early morning departure out of DTW. Ramp was mostly covered; making following taxi lines more difficult. We were cleared to taxi to the Central Deice Pad via [Taxiways] K; E2; and E3. Nowhere on our charts is E3 shown. E2 is shown going all the way to the deice pad. After searching unsuccessfully to find Taxiway E3; we queried Ground and they informed us to follow the routing shown as E2 on our charts to the deice pad (Spot 7). It would be nice if this were corrected (E3 shown) on our charts to avoid adding this additive condition every time any crew deices in the frozen tundra of Detroit.
An Air Carrier Captain reported taxiway E3 at DTW is not published on their charts.
