179th St Access Management and Circulation Plan

CPZ2021-00013

Planning Study Area

Project Summary

Financial investment and new development growth are expected to change the 179th Street corridor within the Vancouver Urban Growth Area, from Northwest 11th Avenue to Northeast 50th Avenue. This planning study evaluated the future planned streets to develop interim and long-range multimodal corridor plans for the corridor and guide future circulation and access decisions. The proposal is aimed at promoting safety and mobility of the future principal arterial while balancing the infrastructure and utility needs of development.

Purpose and Need

The purpose of this project is to provide a cohesive circulation and access management plan for the study corridor to guide future infrastructure improvements including access locations, intersection control and facility cross-section elements.

The current topography of 179th Street contains significant hills and valleys. Improving 179th Street to a 4-lane street will require “cuts” and “fills”. Future access locations on/off 179th Street need to be considered for safety of the residents while preserving the mobility for all users.
