I would think that in many places, the soil immediate to the road surfaces picks up the salt deposits. In the case of street runoff, the Great Lakes probably are not that much different than looking at the salinity of flowing water in any big city, whether it's Philadelphia, St. Louis, Winnipeg, Denver, etc.
Some of the biggest salt deposits in the world are right underneath the Great Lakes. Miners are literally mining salt deposits underground beneath the lakebeds.
