Ulju-gun Invests 1.7 Billion KRW to Replace 19 Old Protective Walls

Ulsan Ulju-gun announced on the 18th that it will carry out a replacement project for aging vehicle guard facilities in the region.

After investigating the condition of the aging concrete guard walls, Ulju-gun will invest approximately 1.7 billion KRW to replace them with flexible guardrails at 19 locations, including Dongbu-ri, Eonyang-eup.

The existing concrete guard walls installed on roads in Ulju-gun have been found to have deteriorated in performance due to aging and do not meet the standards according to related guidelines.

Guardrails are classified into rigid and flexible types. Rigid guardrails are usually made of concrete and have excellent vehicle containment ability, but they have the disadvantage of transmitting impact to the vehicle during collisions, which can affect occupant safety.

On the other hand, flexible guardrails generally refer to guardrails made of steel. Although they are more expensive and complex to install, they can absorb vehicle impact, reducing the effect on occupants. When open-type, they also offer better driver visibility and views.

The grades of guardrails range from SB1 to SB7 according to related guidelines. Higher strength is effective for protecting against large vehicles but has lower impact absorption, resulting in reduced occupant safety. For low-speed zones with design speeds below 60 km/h, SB1 or SB2 grades are recommended.

Ulju-gun plans to install SB2 grade guardrails, which are most suitable for vehicle protection and occupant safety.

An official from Ulju-gun stated, “We will continue to identify sections where vehicle guardrails are aging or need installation to create a pleasant road environment and do our best to prevent safety accidents.”
