State Road 708 (SR 708) is a 3.682-mile-long (5.926 km), east–west thoroughfare in Riviera Beach locally known as Blue Heron Boulevard.

State Road 708 begins as Blue Heron Boulevard at an intersection with Bee Line Highway at the southern end of the VA Hospital.

The road heads east towards its first stoplight at Military Trail (SR 809), with a mix of residential and commercial areas for the half mile between Military Trail and the interchange with Interstate 95 (I-95).

East of I-95, SR 708 passes through a few businesses, before crossing a canal, and then becomes almost exclusively residential with some commercial mixed in for the rest of the route.

Blue Heron Boulevard then jogs to the north just prior to meeting Old Dixie Highway (CR 811), and heads east through a dense residential area before terminating at US 1.
