Traditional left-turn lanes are not always practical or able to adequately address congestion problems at an intersection. How turns are allowed and indicated at intersections significantly impacts the intersection’s safety and efficiency. Innovative intersection designs provide alternative ways to accommodate left-turning movements. These include:
- Dutch Junction
- Continuous Flow Intersections
- Median U-Turn (Michigan U or ThrUturn)
- Quadrant Roadway Intersections
- Modern Roundabouts
