 From exit 40 in Norwalk, the merge with Route 7 all the way down to exit 34, the Longridge Road exit in Stanford, then clears up by the time you get to exit 31 in Greenwich, then okay to the state line. You run into heavy traffic on the southbound side of the Hutchinson River Parkway, south of I-287. 287 itself is good between Portchester and the Hutch, and the southbound side and northbound side of 95 clear between Portchester and New Rochelle.
