Celebrating 70 Years of Steel Guardrails: A Wreck in Bochum's Rearview Mirror
Seventy-year-old steel guardrail experiences its first crash in Bochum - "First crash involving a 70-mph steel guideboard occurrence reported in Bochum"
When a trailer plunged into the abyss on Bochum's A40 motorway, the unsung hero was the 70-year-old steel guardrail. Just three days on the job, it prevented the bitumen truck from tumbling down the ravine, ensuring it rolled back onto the asphalt.
First installed in 1955 as a pilot project near Bochum on the A40, this trusty guardrail initially served as a bright, visual marker for the roadside. However, insights from the "Street and Highway" journal in 1960 recognized its true value for traffic safety, eventually replacing the outdated "Alpen crossings."
The steel guardrail was inspired by American systems in use since the 1930s. In Germany, two diverse construction methods known as the A-profile and B-profile have been implemented, each with its unique advantages. Despite attempts to unify, regional differences remain, with around 80% of German guardrails featuring the B-profile while Rhineland-Palatinate and certain northern regions cling to the A-profile.
But fear not—these regional nuances have negligible influence on traffic safety. Modern guardrails boast an expansive "crush zone" and clever safety features to maintain balance and keep heavy vehicles on the road.

Interestingly, the historical development and regional variations in steel guardrail usage in Germany provide a fascinating glimpse into the evolution of road safety infrastructure, local policies, and accident outcomes. Over time, industry-leading standards such as the DIN norms have continuously refined the design of guardrails to meet criteria for durability, impact resistance, and visibility.
As Germany's heartland, Bochum serves as a valuable case study for the strategic placement of guardrails along highways, major arterials, and accident-prone curves. Factors influencing their placement often include traffic volume, roadway topography, and local accident statistics.
Ultimately, steel guardrails, like the one that held firm in Bochum, have proven invaluable in reducing traffic fatalities and injury severity. Modernization in Germany includes the integration of energy-absorbing terminals and improved visibility features for even greater safety performance as part of broader accident prevention strategies.
- As Bochum continues to implement community policies focused on traffic safety, the significance of vocational training for skilled workers who construct and maintain guardrails cannot be overstated.
- In the evolving landscape of road safety infrastructure in Germany, the integration of vocational training programs in schools and technical institutes could foster new generations of professionals who specialize in guardrail design and manufacturing, contributing to continued advancements in sports safety equipment, such as soccer goalposts and basketball hoops that incorporate guardrail technology.
