I looked at the google maps suggestions and they dont look terrible. The most direct routes look the least fun. I would avoid Rt 6 and Rt 44. On the suggested google route, i would navigate off Rt 101 and use less traveled roads to get to Central Pike and stop and see Swamp Meadow Covered Bridge, one of only 2 in RI. Once you cross the Reservoir you can climb up to Central Ave which will take you right into the Olneyville section of Providence. Celebrate with a taco, weiner or Cuban. Traffic is busy in Olneyville Square but Ive never had an issue and ride through there all the time.
