The distance beyond the edge of traveled way that should be clear of any non-traversable hazards or fixed objects. 16. Roadside Hazards. A general term to describe roadside features that cannot be safelyClear Zones - Safety | Federal Highway AdministrationBy creating Clear Zones, roadway agencies can increase the likelihood that a roadway departure results in a safe recovery rather than a crash, and mitigate the severity of crashes that do occur. A Clear Zone is an unobstructed, traversable roadside area that allows a driver to stop safely, or regain control of a vehicle that has left the roadway.

The guardrail should be raised to 29 inches, which represents the target height for new installations of strong post w-beam systems. If the pavement work requires the barrier to be moved, then the posts should be carefully extracted and, if in good condition, re-driven at the new location so that the rail will be at 29 inches.
