Project development high priority curves

Project Development – High Priority Curves

Three ways for a Curve to receive a project:

Curves w/ Existing Chevrons

High Priority Curves

and those in close proximity

PROJECT:

All Curves on Roadways*

Install/upgrade Chevrons

+2’ Shoulder Paving

+Rumble Strip

High Priority Segments & Critical Curve Radius

Note: Gravel roads were considered if the segment experienced a high frequency of severe curve-related crashes.
