问了谷歌,跟我说的一样:
At 5 p.m. in Ottawa, westbound traffic on the 417 (Queensway) is generally less congested than eastbound, but both directions are busy during peak evening rush hour (around 3:30 PM - 6 PM); however, eastbound often sees heavier flow towards the suburbs and westbound towards downtown, making eastbound (towards Orleans/Navan) busier for commuters heading out of the core, while westbound (towards Kanata/Barrhaven) is heavy with downtown workers returning home. Expect significant slowdowns in both directions, but check live maps for specific incidents.
