The Town of Cary’s 2016 Capital Improvement Program identified the FY2016 Intersection Improvements Project (ST1251) as a mechanism to help meet the Town’s future transportation needs.
With a goal to address pedestrian, bike, and vehicular level of service and congestion at several key intersections, the Town received partial Federal-funding for the projects to improve connectivity, safety, and quality of life for citizens and visitors to the area.
SEPI was selected to work in partnership with the Town for the assessment and subsequent design improvements of five separate intersections under the FY2016 Intersection Improvements Project.
SEPI began the process by providing initial data collection and conceptual design plans for each of the five intersections. Staff utilized their depth of experience to deliver engineering design services for the development of construction plans including surveying; preliminary roadway design plans; environmental screening; hydraulic and stormwater management; traffic signal design; signing; 7,500-LF of pavement markings; traffic management plans for the 65% right-of-way plans; and final construction plans. SEPI also provided construction cost estimates for each intersection as well as public involvement.
Given the active urban environment surrounding the intersections, solutions to enhance pedestrian facilities included the addition of MUTCD and ADA compliant curb ramps, traffic signal and ITS modifications utilizing Leading Pedestrian Intervals to provide for safer pedestrian crossings, and restriping of existing crosswalks to provide better visibility.
Additionally, SEPI is providing landscape architecture services for streetscape design at these intersections. Using the existing, adjacent landscape as a guide, staff are developing a landscape design that will seamlessly blend these improvements back into the overall streetscape along their respective corridors.
