Benefits of a Diverging Diamond Interchange:
A diverging diamond interchange is when traffic lanes cross over at each end of the bridge to eliminate left-hand turns across opposing traffic. Instead of making a sharp left turn, drivers veer to the left for access. These
interchanges improve traffic safety and mobility and cut overall traffic delays up to 60 percent.
Safety benefits of diverging diamond interchanges include:
• Fewer conflict points.
• Conflict points are spread out throughout the interchange.
• Better sight distance at turns.
• Wrong way entry to ramps is extremely difficult.
• Pedestrian crossings are shorter.
If you must stop on the freeway because of an emergency, take the following actions:
- Park your vehicle on the shoulder, as far from the main roadway as possible.
- Open the trunk and raise the hood or tie a white cloth to the radio antenna or a door handle.
- Use hazard warning lights, if you have them.
- If you have flares or reflectors, place them from 100 to 500 feet behind your vehicle on the right edge of the main road.
- Stay with your vehicle, if possible. If you must leave your vehicle, do not walk on the area of the highway reserved for vehicle traffic. This is illegal and extremely dangerous.
