When you provide a bypass for the trucks and doublewide homes, the retailers do benefit. Enthusiasts of traffic calming point to places like Winter Park, near Orlando in Florida, where traffic moves very slowly through narrow, tree-lined streets, with plenty of parking and the kind of lively retail scene that seems to be deserting other US cities. NOT ONE of the double-wide houses is making a downtown delivery. This is their shortest route. They actually are forced by current truck route rules to detour to downtown Goshen.
Many companies have several plants and they move lots of inventory from plant to plant.
This so-called local traffic could move around Goshen on a bypass rather than first going downtown to get on another highway. A properly designed limited access bypass accommodates industry and commerce on the edges of the city. It allows the trucks servicing the edges of the city to exit the city, no matter which way they are headed. The center of the city becomes off limits to through trucks and once again becomes a friendly and inviting place for people. This Traffic Congestion theory from a Wall Street Journal article also states that we should not widen the streets to facilitate faster traffic flow.
