The Jubilee Parkway is a pair of parallel concrete viaduct bridges that carry Interstate 10 across Mobile Bay from the George Wallace Tunnel on Blakeley Island in Mobile, Alabama eastbound to Spanish Fort/Daphne, Alabama. The bridges are similar in design to the pre-Hurricane Katrina I-10 Twin Span Bridge near New Orleans, Louisiana. Each of the two bridges is two lanes wide, for a total of four lanes, and 7.5 miles (12.1 km) long. The parkway was completed in 1978 and crosses the northern portion of Mobile Bay, running roughly parallel to the nearby Battleship Parkway.
