The Wyoming post

DOT uses durable divider to ease problematic roadways

When miles and miles of open highway take on wind, snow, brutal cold, reduced visibility and many other potentially dangerous elements that Mother Nature has to offer—and travel conditions become hazardous—a heavy-duty delineator is a necessity. RubberTough posts (Circle 920) from Safe-Hit Corp., a subsidiary of Quixote Transportation Safety Inc., Chicago, is turning out to be the answer to what had been a nagging, labor-intensive and expensive problem. The posts also are playing a key role in helping motorists safely navigate Wyoming roadways, often under difficult circumstances.

Hit away

It’s a constant challenge to the Wyoming DOT trying to tame the temperament of Mother Nature. According to Steve Murray, area maintenance supervisor for WDOT in Cheyenne, the department originally installed the RubberTough post at the Wyoming Port of Entry to channel traffic into a weigh-in-motion scale.

“Different steel and fiberglass delineator posts that we used got hit every day by over-sized loads, were ruined, and had to be replaced once they broke off,” Murray explained. “That’s when we decided to try the RubberTough posts due to their construction, which we understood would bend but not break when impacted.”

The RubberTough post has a patented swing hinge made of an unbreakable rubber as the flexing point of the post. The unique hinge is constructed of banded, recycled automobile tires that will not shatter, crack or bend out of shape and is resistant to the most brutal weather conditions. After a vehicle, snowplow blade, wind or other force bends the post over, it returns upright. The post itself is made of a heavy-duty plastic tubular extension that resists shattering, cracking or bending out of shape when impacted.

“Due to the early success of the posts at the port of entry station, we begin installing them along different sections of high-impact roadway in the Cheyenne area,” Murray added. “For example, the posts are at the I-25 port of entry between Wyoming and Colorado, on various entrance and exit ramps along I-25 in the Cheyenne area and between Laramie and Cheyenne on I-80.”

Murray said the posts are primarily used for delineation and channelizing along Wyoming’s roadways and also provide a much safer alternative to steel or fiberglass posts that can shear off and present a spearing or puncturing hazard to motorists, their vehicles and tires.

“From a cost and labor standpoint, these posts have contributed significantly for the simple reason we no longer are out there replacing broken posts every month or posts that crack under very cold conditions,” Murray said.

The RubberTough delineator posts in Wyoming are driven into the side of the roadway permanently via a steel spike, which can be driven securely into virtually any soil condition. WDOT used a portable gas-powered driver to drive the posts into the ground. Once installed, the delineator post is 48 in. from ground level for maximum visibility.

“These posts are not necessarily new, high-tech, revolutionary highway safety technology, but they sure are an important product that works for us,” Murray concluded.
