The city of Ballwin is buying two large electronic message sign boards to replace existing ones that no longer work. But the city has been very specific about the kind of boards it is going to buy.
Ballwin’s Board of Aldermen approved the purchase of the boards at its May 14 meeting. Total cost of the devices from Traffic Control Co. of Valley Park, including some optional equipment such as solar panels and additional batteries and chargers, is $29,385.
The sign boards will be easy to spot. They are 4 feet tall and more than 7 feet wide.
Both the police and public works departments will use them for traffic diversion or guidance during special events and for communicating important public safety information.
The signs have built-in touchscreen control capability to ensure the process of changing messages is quick and easy. The control mechanism is password protected and there is no way to access it via a laptop or plug-in device.
The city wanted to avoid the signs being the target of possible hacking activity.
Traffic Control’s bid was the only one submitted. The city’s 2018 budget included $30,000 for the devices.
