The Recommended FY 2005-2010 Six-Year Highway Plan contains over 1,000 major projects across the Commonwealth. In addition to the revenue assumptions and individual project listings by county, the following pages include a set of maps that illustrate the locations of many of the major highway improvements in both rural and metropolitan areas. The maps further illustrate the highway system involved by segregating projects into two primary categories, "system preservation" and "system upgrades and additions." The maps are not sufficiently detailed to precisely locate every project, but do indicate the extensiveness and relative statewide distribution of planned project activity.
