Reduced speed limits at two rail crossings on State Highway 1 in Mid and South Canterbury will remain in place at least until October.
The NZ Transport Agency has put in place temporary reduced speed limits of 50kmh at level crossings at Winchester and Chertsey, after the sealed and curved approaches deteriorated in hot summer conditions.
The seal “bled”, or melted, the surface adhesion was reduced.
If it rained, drivers were much more likely to slide on the road surface unless they were travelling at the temporary 50kmh speed limit.
Transport agency system organisation needed to do a full road repair at the level crossings in spring or summer.
“In the meantime, for everyone’s safety, we will keep the temporary speed limits in place until these full repairs are completed. That will be until October at least.”
Crews have completed minor road repairs at both sites to reduce the potential for slipperiness in wet conditions, but that is only a short-term solution.
