I used to work in RI....95 coming up into Providence bogs up for the morning and afternoon commutes, as does 195 and the 24 area as you're coming up from Newport.....Are you thinking Warwick/Cranston/Wakefield? Rte 4 (I think) is slow going as it intersects 95 north to get up into Providence.The bridges near Newport are only a hassle in the summer, heavy on the tourists. Some of the RI news station websites would have traffic pages that would give you estimates of commuting times I bet.
