A n a l y s i s R e s u l t s The analysis showed differences in the following factors: � Impacts to historic districts* � Spacing of intersections to improve traffic flow � Economic development opportunities (City Study) These factors all favor the Mound-Fulton Alternative * Federal laws specifically protect historic resources and require agencies to avoid them when there are prudent and feasible alternatives.
