A new automated lane reversal is in operation on Memorial Drive between 9 Street and 14 Street N.W. during afternoon rush hour from 3:30 p.m. to 6:30 p.m., Monday to Friday.
This lane reversal means the westbound lanes increase from two to three, to allow for increased traffic leaving the downtown core.
Remotely controlled and visible from The City's Traffic Management Centre, this system consists of motorized gates and overhead LED lane control signals.
The Memorial Drive lane reversal pilot project was initially a manual operation utilizing pylons and barricades. Beginning in 2006, it serves over 440, 000 vehicles per year saving westbound traffic up to 3 minutes during the evening peak period, an eternity to those stuck in traffic.
Here is a video of the lane reversal.
