As it approaches King Street, two lanes of Erb Street split off to the left and become Albert Street. At the moment there is an orderly flow of traffic onto Albert. The Region's LRT proposal, however, creates a problem here, because the LRT is going to run against traffic right through the lanes that are splitting off.
Here is a snippet of the Region's LRT map with some annotation by me (you can see the complete unadulterated map here):
Erb Street is one-way with traffic running towards the top of this map. The LRT (represented by a thick pink line) is also one-way but is running towards the bottom of this map, against traffic. Traffic on Erb that wants to split off to Albert will have to cut across the LRT tracks. The LRT is scheduled to run every 7 minutes, but there are no traffic lights to protect cars that have to drive on the tracks towards the oncoming trains. It's not even possible to put a stop sign here, unless they put one in the middle of Erb Street.
I don't know what this will do to traffic flow, but it seems to be extremely unsafe. This crazy plan is going to cause accidents. If it does, the drivers are going to have a good case for a law suit against the city and the Region.
Update: At the 11th hour, Regional Councillor Sean Strickland got the region to change the route so that it will not turn down Erb, but instead run along the railway tracks through Waterloo Square. Consequently, this problem went away.
