Alternative Intersections/Interchanges: Informational Report
The U.S. Federal Highway Administration has released a report that explores four intersection and two interchange designs that have potential advantages over conventional at-grade intersections and grade-separated diamond interchanges. Issues explored in the report related to each alternative treatment include geometric design, operation and safety, access management, costs, construction sequencing, environmental benefits, and applicability.
The six alternative treatments covered in the report are displaced left-turn intersections, restricted crossing U-turn intersections, median U-turn intersections, quadrant roadway intersections, double crossover diamond interchanges, and interchanges.
