At the t-junction with Donway Drive, 2nd line west starts going northbound with a bridge over the 401. Going up the bridge will naturally lead to building up speed until you get to the apex of the bridge, where you can then speed up easily to 100+km/h if you so choose. On the way down, there’s an undercover cop in dark brown on the southbound side pulling multiple cars over for doing even 20 over the limit (it’s a 50 zone). I haven’t seen this for over half a year until today after the evening rush hour – had to find out the hard way.
