St. Petersburg's deadliest road corridors

Ranked by the number of people killed, these are Pinellas County's most dangerous roads:

US 19 is the same high-speed surface highway that earns Pasco County its grim reputation, and it does not improve as it runs south through Pinellas — a wide, fast corridor lined with driveways, bus stops, and pedestrian crossings. It killed 60 people here, far more than any other road. I-275 adds large injury totals from interstate speed and volume, while surface arterials like SR 693 (66th Street / Tyrone Boulevard), Seminole Boulevard, and 49th Street N mix heavy local traffic with older drivers and a high share of pedestrians and cyclists.

What this means if you were hurt

A road's reputation doesn't decide fault — Florida looks at what each driver did in the specific crash — but a documented danger pattern is useful context. If you were injured on one of these roads, the priorities are the same: get medical care within 14 days to preserve your PIP benefits, document the scene, and understand your coverage before talking to an insurer.
