U.S. Route 98

Its eastern terminus is Palm Beach, Florida, at State Road A1A (SR A1A) near the Mar-a-Lago resort.

[citation needed] At Hattiesburg, an interchange with U.S. Route 49 provides four-laned access to Gulfport (to the south) and Jackson (to the north).

Passenger car traffic passes directly into town under the Mobile River via the Bankhead Tunnel.

The existing route between Semmes and the Mississippi state line is a two-lane undivided highway, and widening the route has been delayed due to a lack of budget and concern over pollution of Big Creek Lake, which supplies drinking water to the city of Mobile and other area towns.
