I wouldn't say not having a sidewalk is an embarrasment for a main entrance, considering it's a major aerterial road primarily suited to traffic flow. A sidewalk along a 5 lane road won't change people's perceptions of Edmonton, but developing a vacant lot with a higher and better use definitely would help.People who work in the area. People who don't have access to a car. People walking to grab lunch while working. Someone who takes transit which stops 500m from their destination who's maybe mobility challenged and can't properly navigate the complete lack of infrastructure there now. Etc, etc, etc.
It's the primary entrance to our city, it's an embarrassment.
