It depends on where you count from. If you count near the bottom, there are 11 lanes across in one direction, meaning a total of 22 lanes which matches the 26 in the other comment if you include and exit and enter lane on either sided. The 401 has 3 lanes in the collector’s and 3 lanes in the express meaning 12 lanes total for both directions you could add 4 lanes which go to/from the collector and express for 16 lanes total. Is this similar to the 14 lanes you claim? Sure. But the 401 and 400 highways do not get nearly as wide as the one in the image at its widest.
