SW Marine Drive & 16th Avenue Intersection Redesign

University of British Columbia. Campus and Community Planning

This final design report presents the culmination of a collaborative effort between The team and UBC Campus and Community Planning (CCP), marking a significant milestone in the transformative redesign of the SW Marine Drive & 16th Avenue intersection. Central to this vision is the creation of an infrastructure that exemplifies safe, multi-modal transportation, embraces sustainable practices, and enhances the spatial quality of the UBC campus. The final design features a shifted intersection accommodating a stormwater detention pond at the low point of the project scope to reduce cliffside erosion risk and manage water sustainably on-site with little maintenance. Active transportation is promoted through extended trails, crossride crossings, and realigned bike lanes – all converging to encourage a shift towards more sustainable transit options. The roundabout varies from one to two lanes, depending on the leg to better accommodate specific traffic demands, slow drivers down by introducing some congestion, and decrease crossing distances for cyclists. There will be rectangular rapid flashing beacons (RRFB) on W 16th Ave. along with signage warning drivers to decrease speed to 30 kph, enhancing the safety of pedestrians and cyclists crossing. The desired speed from SIDRA analysis is 38.7 kph. Lastly, all lane widths will be decreased to 4 m and the northbound leg of SW Marine Dr. will be decreased to one lane to further reduce driver comfort and vehicular speeds. Aesthetically, the design integrates a visual "gateway" into the campus, complete with Musqueam art, providing users of a sense of arrival and indigenous presence on campus. The team’ engagement strategy has proven to be effective and has been instrumental in shaping a design that not only meets technical and functional requirements but also resonates with the cultural and social fabric of the campus community. The total estimated cost is $3,105,800, calculated based on material costs, hourly rates, and fixed fees. Construction will begin May 1, 2024, with completion estimated to be the September 27, 2024.
