The final design of the Phase 4 Wesbrook Mall Redesign will maximize safety for all transportation users, while minimizing costs and tree removals across the corridor. Active transportation modes and transit reliability was deemed as the main priority in the final design. This includes a 3.0m travel lane, 3.4m bus lane, and a 2.0m bike lane on the northbound (NB) side in place of the existing parking lane. Similar dimensions are used on the southbound (SB) side, with parts of the median removed to create space for a protected bike lane and on-street parking. A 35m long underpass with dimensions of 3.3 x 3.1m (HxW) provides a safe and efficient pedestrian crossing path across Wesbrook Mall. Blue Light Emergency Phones, fire suppression systems, and lighting enhances user safety. Impeller pumps with jellyfish filters are used to remove water from the underpass during heavy precipitation events. Green Infrastructure in the form of permeable pavements and rain gardens are utilized to reduce polluted runoff and retain stormwater on-site. Construction is scheduled to begin in June 2022, with the expected completion date of March 2023. The final class A cost estimate for the project is $4.5 million.
