Note: There's no extra charge to call 511 from your mobile device in Massachusetts. Your normal mobile charges (if any) will apply, just as they would with any other call you make.
For regional traffic reports, I like Boston radio station WBZ 1030-AM for their "Traffic on The 3s". (Every ten minutes, e.g. 10:03, 10:13, 10:23, 10:33, etc.)
1030-AM's reports cover all the major roads leading to Cape Cod from Boston and the North Shore, as well as from Western and Central Massachusetts.
That includes: the Massachusetts Turnpike (Rt. 90), I-93, I-495, Rt. 3, Rt. 25, and the Bourne and Sagamore bridges.
For local road and bridge traffic conditions here on the Cape, we tune to WQRC 99.9-FM, a Hyannis-based radio station, for hourly (in-season) traffic reports.
