South Portland Relocation

For this three mile project, Johnson & Associates designed approximately 1.5 miles. This relocation was designed to bring industrial and commercial development to the area west of the Will Rogers Airport, with potential access to the airport’s landing strip. This project involved site inventory & data collection, creation of survey information, traffic studies, signal design, drainage analysis & design, schematics, CDs/bidding, and construction administration. Challenges included the design of a boulevard street with superelevation, a complete analysis of the drainage basin, the design of 16 storm sewer crossings (each with their own local drainage system), traffic analyses, and 20 year growth projections, grading, & excavation calculations for potential future industrial development.
