Each direction of traffic on this highway includes 3 lanes of motor vehicles 3.75m wide and one emergency lane 3.0m wide.

Speed ​​regulations

The prescribed speed for motor vehicle lanes on the Phap Van - Cau Gie expressway is as follows:

Lane 2	100km/hour	70km/hour
Lane 3	100km/hour	60km/h

Deputy Director of the Vietnam Road Administration - Nguyen Thanh Hoai, said: The adjustment of the two expressways Hanoi-Hai Phong and Phap Van-Cau Gie was carried out based on the evaluation of the results of the vehicle lane separation pilot, the proposals of the management units, and the document of the Traffic Police Department on the adjustment of the lane separation plan.

For this elevated route, the Vietnam Road Administration requires that BOT Phap Van-Cau Gie Joint Stock Company be the management unit responsible for organizing implementation, adjusting and supplementing road signs.

The company also needs to notify and send the approved traffic organization plan to the Traffic Police Department on duty on the route and organize the dissemination and propaganda of the plan.

According to the Vietnam Road Administration, lane division based on vehicle weight and type will help traffic on key highways become safer, more reasonable and smoother, while also limiting the situation of large vehicles mixing with small cars in high-speed lanes.

The Department also assigned the infrastructure management units and Road Management Area I to coordinate in closely inspecting and monitoring the implementation process to ensure compliance with the new plan.
