The intersection at Front and Spadina is a constant traffic jam with street car tracks being ripped up every couple of years and now, there's construction of a new condo building on the north west corner. However, I've always been annoyed by the no right turn on a red when driving east on Front wanting to turn south onto Spadina for access to the Gardiner. The light for eastbound traffic is only green for 17 seconds which is never enough, especially when pedestrians disobey the "cross on the other side of the street" sign.
When there is an advanced green arrow for northbound Spadina traffic to turn west onto Front, why can't we have a green arrow to allow more cars to turn right onto Spadina southbound at the same time? I try to avoid this intersection whenever possible, but the access to the Gardiner west of the Ex is always also a total mess. Please help!
