Redesign of Intersection at 16th Avenue / SW Marine Drive : Final Design Report

University of British Columbia. Campus and Community Planning

Team 13 has completed a detailed redesign of the intersection of SW Marine Drive and 16th Avenue. The current intersection has not changed to meet the needs of a growing UBC Point Grey population, with issues including high traffic speeds, poor cyclist and pedestrian safety, erosion of Point Grey cliffs, and no sense of arrival to campus. The redesigned intersection features a turbo roundabout for traffic control, serving to both control traffic speeds entering campus and help prevent collisions with dedicated turning lanes. Road curvature, reduced lanes, and textured roadways further help to slow traffic approaching campus. Revamped bike lanes protected by sensor activated lights and rain garden buffers address cyclist safety and comfort, while a steel truss pedestrian overpass spanning 16th Avenue completely ensures the safety of pedestrians. Extensive rain gardens and reductions in impervious areas serve to retain all stormwater onsite and prevent erosion. A recycled plastic UBC sign in the center of the roundabout commissioned from indigenous artists welcomes visitors to campus, and affirms UBC’s respect for the traditional and ancestral lands of the Musqueam people. The design conforms to all Ministry of Transportation and Infrastructure requirements, and guidelines from the City of Vancouver Engineering Design Manual and Accessibility Guides. The Class A cost estimate predicts a project cost of $2,246,000 including $33,000 in annual maintenance. Construction in four phases is designed to begin May 1st, 2024, completing September 12th, 2024. Traffic management plans are set to keep access through the intersection open using temporary traffic lights for 3 of 4 phases, with detours for one traffic route required for the fourth phase. Detailed design drawings, 3D models, SIDRA traffic analyses, structural and foundation calculations, and stormwater management analyses are included in the appendices of this report. Together, the design package is ready to be sent for construction.
