WisDOT's interactive traffic count map is located
here in case anyone wants to pan around and see what the numbers are for themselves.
Not to be pedantic, but the highest AADT on 794 is 94,400. This drops to 67,700 "east of Water St". Then down to 40,000 on the Hoan.
Adding up the AADT for all the ramps between the Hoan Bridge and the Milwaukee River is 25,900. Subtract that from the Hoan's 40k means a thru traffic AADT of 14,100.
Not that impressive if the argument is this entire freeway is needed for the city's freeway system to function. 14k is what Water Street has downtown.
These numbers bolster my position that the city will be fine if 794 doesn't go all the way through downtown as a freeway.
