A4−2: Work Zones Designed at the Posted Speed
In instances where traffic realignment is required through the work zone, the realignment (e.g., reversing curves and super elevations) is designed for the posted speed rather than the reduced work zone speed.
REASON(S) FOR ADOPTING:
Simply posting signs with a lower speed through a work zone, without any enforcement, often does not result in reduced speeds.
The biggest benefit is that safety is enhanced through the project.
MOST APPLICABLE LOCATION(S)/PROJECT(S):
Any type of work requiring the realignment of traffic. This practice is considered for every project. It is most effective for high−volume/high−speed locations.
