Regarding the many accidents on the Kensington Expressway, especially at the westbound exit to the Scajaquada Expressway, I suggest the addition of "rumble strips" to all lanes. Drivers bearing left to head downtown or bearing right to exit might just be jolted enough to slow down to a reasonable speed. This should be a quick and relatively inexpensive project.
In addition, it is absolutely necessary that the police find a way to patrol and ticket cars for excessive speed and lane-changing. Too many drivers on this road are dangerously aggressive in their driving habits and show no respect for other drivers.
