Why Can’t People Maintain Speed Limit Across The Twin Bridges? [RANT]

I drive the Northway up and back to work everyday, and I am baffled by one thing almost daily.

The Northway is exactly 3 lanes wide North and Southbound, up to and including over the Twin Bridges. Why the hell can people maintain the speed limit up to and over them in the morning an afternoon commute.

If there is an accident, that's one thing and I understand it. On many morning and afternoon commutes there are not any accidents and when you get to exit 6 or 7 Northbound, or exit 9 Southbound traffic slows down until you get over the bridges. There's just simply no reason for it. Do the speed limit!

Am I the only one that gets frustrated by this? Let me know.
