This project included design phases I-IV for a 4.2 mile long arterial. Tasks performed for the project include: topographic survey, base-mapping, drainage structure, inventory and underground utility location identification. A draft design report was developed based on a dated EPP; it included a new accident analysis, traffic volume turning counts, and intersection and corridor Level of Service analysis. The draft design report included three improvement alternatives which were: performing intersection improvements, adding a third lane in select locations and adding a two-way left turn. The entire project was also evaluated for bicycle lanes. Subsequent to design approval, final design plans were developed including right-of-way acquisitions, over 30 traffic signal replacements, new turning lanes, full depth pavement repairs, milling and filling, drainage repairs, new sidewalks and curbs.
Responsible for the preparation of the design report, preliminary and final design plans, specifications and construction cost estimate. A Phase I Environmental Assessment was performed for the project as well.
