Okay re: your trip, my guess is that both the GW and the TZ are going to be about the same. When you get 20 miles or so from GW, you can check NewsRadio 880 AM for traffic and compare.
Now since you love The Merritt so much, I can take you from GW Bridge to The Merritt via similar parkways only and, of course with no trucks and Interstate madness and such..
- Toward end of GW, stay to your right. For Henry Hudson Parkway NORTH (the curves and forks get temporarily confusing here, so Go slow on the curve and just make sure you're on The Henry Hudson Pkwy (Rt. 9 NORTH)
- Henry Hudson Pkwy's name changes to The Saw Mill River Pkwy as it crosses over NYC line into Westchester County. Same Road, just name change so don't get confused.
-Get off Saw Mill Pkwy at the Cross County Parkway exit (as soon as you see the sign for it, get in the right lane: it comes up fast)
-Cross County Pkwy takes you to Hutchinson River Parkway (North is on the Left) which you probably know and have taken since it ends at the NY/CT Boarder where begins the famed Merritt Parkway (now a National Historic Landmark).
To enjoy your trip even more, check out the Merritt's overpasses. Every one is completely different designed by different architects.
Have a safe trip.
