Effect of Highways on Cities

Most cities are scarred by freeways cutting through residential neighborhoods and downtowns. These highways have multiple commonly accepted negative impacts that include:

  • Long-lasting effects of the original construction such as removal of historic buildings, relocation of poor residents, and division of long-standing neighborhoods.
  • Facilitating suburban expansion at the expense of traditional neighborhoods. Highways encourage automobile use rather than public transportation.
  • Creation and maintenance of a physical separation between formerly connected neighborhoods. Restricted access highways are a physical barrier that prevents people from crossing - what was once a two-block trip may now take 12 blocks. Bridges and tunnel crossings are often unpleasant for pedestrians.
  • High cost of construction and maintenance for the road surface, bridges, and ramps. The complexity inherent in a highway ratchets up the cost of maintenance and construction.
  • Massive amounts of formerly productive land are utilized as circulation and buffer rather than generating taxes through intensive use.

There are numerous pedestrian bridges between major cross streets. Streets like Cottage Grove connect through easily by automobile, bicycle, and foot to downtown amenities.

Generally speaking, it is my opinion that the introduction of highways within city borders has done much more damage than good. The highways themselves have become one of the primary drivers (so to speak) of our dependence on automobiles for personal transportation, economic stimulus, and as symbols of freedom. Instead of planning our cities around people, we now plan them around automobiles.
