Lam DongThe 300 m long bend on Prenn Pass is equipped with Korean technology swivel guardrails, at a cost of 4,3 billion VND to limit damage in the event of an accident.
The information was given by Mr. Vo Ngoc Minh Phat, Deputy Director of Traffic Project Management Board of Lam Dong province on January 31. This is a new technology, the price is quite high, but after testing in many localities, it has been effective. The pass with rotating wheel guardrails is a bend near the Dalanta tourist area that is quite crowded with vehicles entering and exiting every day.

According to the construction unit, the rotating wheels are made from flexible plastic beads. When there is a collision, this guardrail system absorbs the direct impact force through the damping mechanism and transmits the force evenly to the entire structural system including fence bars, swivel wheels and pillars.
In addition, the rotating wheels help the collision force be converted into sliding moment, bringing the vehicle back into the traffic orbit, limiting overturns and multiple accidents. This type of guardrail was previously installed on a trial basis in Hoa Binh, Ho Chi Minh City, Kon Tum, Quang Ninh...

The pass connects Highway 20 - the main artery from the Southeast region to Da Lat, often crowded and overloaded on weekends, holidays and Tet.
