  • With new concrete pavement now extending from Veterans Road to Head Lane on the Stardust Drive extension, it’s only a matter of time before the roadway is open to traffic. In advance of that plans are being made to ensure that traffic doesn’t go too fast on Stardust, especially on the portion that goes through the residential neighborhood between Head Lane and Rosewood Drive.
    At the recent meeting of the Traffic Committee, sites where traffic-slowing devices could be installed were a topic of discussion. City Manager Jeff LaGarce says plans have not yet been finalized.
    “We are still studying Stardust,” he said. “We will have four-way stops at Stardust/Clover and Stardust/Head. We don’t know if there will be any others. We’re tentatively planning for a speed table on Stardust between Clover and Veterans, between Head and Rose Hill, and possibly between Rose Hill and Munger, but we haven’t made final determination of this yet.”
    The “speed tables” that will be installed on Stardust will be similar to the flat-topped speed hump put in late this summer on Maple Street, between Church Street and Broadway, by Holy Family School.
    That table was installed after Joy Hayward, Holy Family School principal, approached the city about doing something to slow traffic on Maple. In October, Hayward gave a glowing endorsement of the speed table’s effectiveness.
    City officials have favored using speed tables to slow motorists since paying a visit to Arnold a year ago.
    “Arnold uses them very effectively; modeling them after a manufacturers’ unit they purchased. We took those dimensions from them, and can build our own tables to the same dimensions,” said LaGarce.
    According to LaGarce, the speed tables can be tweaked in their size and surface shape to help encourage motorists to adhere to the posted speed limit.
    “A 5-inch tall speed table requires vehicles to slow more than a 4-inch table. Slightly rounded-top surfaces require vehicles to slow more than flat-top surfaces. Tables along larger streets may be only 4 inches in height, and the tops flatter. Unless it’s a school zone or other unique situation, we don’t generally want motorists to slow to 15 mph; rather, we want them to slow to 20 mph or 25 mph - whatever the posted speed limit is we want them to drive,” he said.
