On/around November 16 the 23 Avenue and 111th Street intersection will undergo a major lane shift that will last approximately 2 years. The change is needed for construction of the LRT underpass which will allow trains to travel beneath the intersection. The city says the majority of work will take place on weekdays between 7 am and 5 pm but some construction may occur on Saturdays, depending on the weather.
The DailyHive article below has maps illustrating the changes that will affect the intersection.
