Problem with the Hutch/Merritt is that it can get very congested too, especially around the rush hours.
Most people don't remember to maintain speed while going up those steep hills. Also, a huge bottleneck is tha t!@#$#@!@#$ Sikorsky Bridge in Stratford.
If it is raining or snowing, AVOID the Merritt Parkway. There's always an accident a mile under slick conditions.
