Project Development – High Priority Curves
Three ways for a Curve to receive a project
1/24/2011 3
High Priority Curvesand those in close proximity
Curves w/ Existing Chevrons
All Curves on Roadways*
High Priority Segments & Critical Curve Radius
PROJECT:Install/upgrade Chevrons+2’ Shoulder Paving+Rumble Strip
Note: Gravel roads were considered if the segment experienced a high frequency of severe curve-related crashes.
