PLANNING/DESIGN FEATURES AND CASE STUDIES IN FREEWAY RECONSTRUCTION. PART I

A primary reconstruction feature of the freeway proper embodies the strengthening or replacement of the traveled way pavement, usually in combination with widening to increase the number of traffic lanes and to provide adequate and continuous shoulders. An important goal in this process is the need to maintain traffic along the freeway with little reduction in travel speed and capacity. Also of significance is the objective to accomplish the improvement within existing right-of-way or with only occasional taking of adjoining property, and to confine traffic movements and construction operations within such right-of-way.
