Alexander Avenue and Route 347 — Accident History

Alexander Avenue and Route 347 is a Long Island intersection where we've tracked 13 reported crashes since Jan 2026. Intersections like this — where two significant corridors meet at grade — carry disproportionate crash risk compared to mid-block segments because of the higher number of conflict points: left turns across oncoming traffic, right-on-red entries, and pedestrian crossings all converge at a single signal cycle.

The most recent reported crash here. Our dataset runs through Mar 11, 2026.

Cover your brake on approach. Intersection crashes at Alexander Avenue and Route 347 are predominantly rear-end and angle collisions — both of which reward drivers who enter the signal zone at a slightly reduced speed with their foot hovering over the brake pedal. The moment the signal cycle changes is when reaction-time matters most.

Never assume the green. Even with a protected-green signal, scan both sides of the intersection before entering. Red-light running is the single most common cause of severe angle-impact crashes at New York State signalized intersections.

Account for pedestrians. Most Long Island intersections lack the long pedestrian phases of denser urban areas, and walkers routinely cross mid-phase or against signal. Pair that with the sight-line obstructions typical of commercial corners and a cautious approach is the single best risk mitigation available to you.

If you need an alternate. When this intersection is blocked or heavily congested, check 511NY for live conditions and consider parallel streets one or two blocks away — suburban grids usually offer a workable bypass without forcing a significant detour.
