Eugene divides streets into five <br />categories called functional classifications (FC), each representing a different volume and <br />type of vehicular usage. <br />MAJOR ARTERIAL (FC-1) -Major Arterials are usually four or more lanes and generally <br />connect various parts of the region with one another within the city and with the "outside <br />world." They serve as major access routes to regional destinations such as downtowns, <br />universities, airports, and similar major focal points within the urban area. Major Arterials <br />typically carry an average of more than 20,000 vehicles per day. Major Arterials receive high <br />priority maintenance. <br />MINOR ARTERIAL (FC 2) -Minor Arterials are typically two or three lanes. These streets <br />provide the next level of urban connectivity below major arterials. In most cases their main <br />4 <br />
