congestion costs
Where it is already installed in the UK, concrete barrier has proven to be maintenance-free. In contrast, steel safety restraint systems need regular repair, tensioning and maintenance. This results in lane closures and traffic congestion that can sometimes last for considerable periods of time.
The hidden cost of these lane closures and delays to traffic can be enormous in terms of the effect on businesses and the environment. This problem is increasing as the road network reaches saturation. The implementation of concrete step barriers throughout the UK will make a real contribution to the free flow of traffic, helping to ensure reduced congestion and reliable journeys for all road users.
