Erdman Anthony provided preliminary and final design services for the
rehabilitation and widening from four to five lanes of an urban principal
arterial through a highly commercialized district of Rte 15. Preliminary
engineering services included traffic accident and capacity analyses, signal
warrant analysis at two intersections, evaluation of various alignments and
intersection modifications to improve capacity and safety, public meeting
participation, and preparation of the preliminary design report. The recommended
design alternative included the rehabilitation of existing asphalt pavement
through milling and asphalt overlays, and widening to provide a continuous
two-way center left-turn lane. Final design involved improvements to the
existing storm sewer system, intersection improvements, I-95 on/off ramp
widening, extensive utility relocations, interconnected signal design for six
intersections, new granite curbing, paved sidewalks, striping and sign layout,
development of special specifications, and construction cost
