Route 15 (Broadway Street)

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 estimating.
