Decorative Traffic Cone or Bollard?

By: Tom Davis Category: Sidewalk Features

Part of the theme on Preston Street in downtown Houston celebrates the water underground in an urban setting. There is more about that in the article here about the Cotswold Program.ConeBollardLeaning.jpg

Underground water in the City is usually seen when looking into a hole at a broken pipe or when a manhole lid is off and you can see inside Traffic cones are typically around the hole to warn traffic away. To symbolize those situations precast concrete cones are placed throughout the Preston St. enhancements. But a cone is not a bollard. In a few places the cones were intended to shield planter beds and keep cars in driveways. We hoped the cars would avoid them. But plants grow and street lights burn out and the cute little concrete cones can not be seen by the drivers–even those that care.

BollardsPrestonCones.jpgOur cones are attached to the sidewalk by four, 3/8″ diameter quick bolts–aka Hilti bolts. Where they were called for to protect planter beds at parking lot driveway they did not work. They do not stop a one-ton car or be easily seen by the driver and so the cones are knocked over eventually. Fortunately there were only a few in those locations and they were saved to use in other locations after being knocked over.

In the non-vehicular locations they look good like at the Manhole Fountain.

Lesson Learned – Do not use small, neat architectural amenities to channel traffic and scare drivers.
