Location & Road Context
Exit 49N sits in Melville along the I-495 corridor in western Suffolk County. The LIE carries some of the heaviest weekend eastbound volume on Long Island, particularly on Sunday mornings when eastbound traffic builds toward the Hamptons.
According to Long Island Traffic’s incident registry, the LIE has logged 98 recorded incidents in the past 30 days and 469 so far in 2026, making this one of the most active corridors on the island. The most recent prior fatal crash on this corridor occurred August 26, 2026. Two other crashes on I-495 were recorded the same morning: a minor incident and a major incident in the HOV lane.

Broader Impact
A full closure of all eastbound lanes at Exit 49N on a Sunday morning diverts traffic onto the Melville service road, which feeds local surface streets through an area dense with commercial driveways. Any delay in reopening past 7 a.m. compounds as eastbound weekend volume accelerates. Suffolk County Police had not issued a projected reopening time as of 8:04 a.m.
