It is very difficult to see the next traffic light when looking south on Memorial Ave from High St. The light, including the next marked pedestrian crossing, is approximately 1 kilometre away. Consider being midway between these intersections and needing to cross the street. During busy times of day it is difficult to find a safe break in traffic and crossing the 5 lanes of traffic is dangerous for anyone with mobility difficulty, at any time. If the pedestrian walks to the light and then back down the other side of the street it could require walking a full kilometre to get where you want to go. Of course, if you have difficulty walking it is dangerous without a controlled crossing, but prohibitive to walk a kilometre to simply cross the street. It is interesting to note that most research into pedestrian behaviour shows that people with ready access to a vehicle will choose not to walk if the destination is more than about 400 m away.
Looking north from High St we see a similar situation. It is possible to just make out the controlled intersection at John St but it is almost 800 metres away. Again, crossing between the lights is difficult and dangerous and yet a prohibitive distance to walk to the lights if you are not close to High St or John St. The more difficult it is for you to cross the street, the more onerous the extra distance to a controlled intersection becomes.
Memorial Ave is not part of suburban sprawl, but is a busy commercial strip which runs right through the heart of Thunder Bay. Having only one safe pedestrian crossing along a 1.8 km stretch of this artery is crazy! The Ontario government recently passed the Enhancing Road Safety in Ontario Act. It allows municipalities to use new pedestrian crossing devices. There are many places in Thunder Bay where these are needed but nowhere more so than along this stretch of Memorial Ave.
