The improvements to Miles Road in McMullen County, Texas, include these solar-powered curve signs with flashing LEDs.

A road project recently completed in Texas includes lighted chevron signs powered by small solar panels.

Hanson provided design engineering for the project for Miles Road and Rhode Ranch Road in McMullen County, which involved repaving the roads and drainage improvements. Miles Road has several sharp horizontal curves that could not be easily straightened. This type of curve can be dangerous when motorists traverse it at speeds higher than advised, which may result in the car leaving the road and possibly striking objects or overturning.

Signs, such as chevrons, alert motorists to the curve. The chevron signs installed on Miles Road have the added benefit of solar-powered LEDs that continuously flash day and night.

Hanson’s services also included construction administration.
