Poorly constructed corners and in-bends can often cause road access or safety issues.
- The grade on the corner has been reduced to improve truck traction. On roads steeper than 1:8 (12%) it is good practice to reduce grade on corners and intersections.
- The corner is wider to accommodate heavy vehicle off-tracking.
- The road has no camber, or is off-camber on steep sections.
- This steep, narrow corner caused trucking issues.
- The corner is too tight for some trucks, causing them to cut the corner (see arrow).
- The inside of the road is benched to improve sight distance to address safety concerns.
