Streets / Sidewalks / Parking

Ensuring that people have a safe, accessible and efficient place to walk, ride bikes, drive, and even park just makes sense. McGill Associates’ transportation planning and design services improve public safety, build regional character, offer a variety of transportation choices, reduce environmental impact, and increase the lifespan of infrastructure. Our projects reflect a keen sense of environmental awareness, as well as cognizance for diverse forms of pedestrian access and while maintaining ADA-compliance. Furthermore, our planning and design process recognizes the importance of promoting healthier communities and considering existing community and regional assets and developing connections and linkages.

case study

CLIENT: Mission Health
PROJECT DESCRIPTION: McGill Associates assisted Mission Health with improvements to the road network adjacent to Memorial Mission and Saint Joseph’s campuses in Asheville designed to improve traffic flow and accommodate future development. The project added a much-needed link between Biltmore Avenue and McDowell Street. The new road, named Hospital Drive, includes a new four-way intersection with Victoria Road to the south and Hamilton Street to the north. The three major roads in the project are four-or five-lane sections with a center landscaped median. The fourth road, Hamilton Street, remains two lanes but with an improved vertical alignment.

Due to the significant grade differences between Biltmore Avenue and McDowell Street, approximately 30’ to 35’ of cut was required at the deepest point in both Hospital Drive and Victoria Road. The new alignment and grade changes necessitated the complete replacement of all utilities within the project limits, including a 12-inch water line, sanitary sewers, storm drainage, power lines, telephone, cable television, fiber optic communications and gas mains. All utilities were moved underground. An additional duct bank was added to facilitate the needs of the new Mission Outpatient Cancer Center. All improvements had to be constructed while maintaining traffic access and utilities to two hospitals, Asheville High School, Asheville-Buncombe Technical Community College (A-B Tech), and adjacent medical offices and businesses.

To maintain traffic, careful phasing of the project was required and was comprised of three major phases.

  • Temporary pavement was installed to allow Victoria Road traffic to continue using parts of the old Victoria Road and Hamilton Street alignments while the southeastern portion of the new roads were constructed.
  • Traffic was shifted to the newly constructed roads to allow the remaining hill to be excavated and the new roads constructed on the northwest portion of the project.
  • The final phase included a surface layer of pavement on the entire project area and completing the project’s landscaping. This provided a clean asphalt surface without remnants of traffic control striping remaining from previous phases.

The project generated roughly 200,000 cubic yards of excess soil, most of which was taken to A-B Tech for the construction of new parking facilities and to expand fill on the western edge of the campus. NCDOT also participated in the project by providing the design and construction of four traffic signals (two new signals, two upgraded replacement signals and temporary with pedestrian signals).

The completed project also includes new pedestrian facilities, a bus shelter and bicycle lanes in keeping with the master planning efforts of the City of Asheville. The right-of-way and adjacent Mission property was landscaped to not only meet City ordinances, but to enhance the appearance of the road corridor.
