Interstate 10 Alabama Descriptions

I-10 crosses from Jackson County, Mississippi and goes through Mobile County in Southwest Alabama. In Mobile, the highway is the southern terminus for Interstate 65. In downtown Mobile, I-10 goes through one of few road tunnels in Alabama, the George C. Wallace Tunnel under the Mobile River. The eastbound approach is posted at 40 mph (60 km/h) because of the sharp curve approaching the tunnel. The highway then crosses approximately eight miles of the upper part of Mobile Bay on a bridge locals refer to as the Bayway. On the other side of Mobile Bay, the highway goes through suburban Baldwin County before crossing the Perdido River into Florida.
