No injuries have resulted. Tully did this by renting Coleman BTK64 MH, four-headed light towers for each construction stage. Other shorter stages required less. The goal, however, is to illuminate the entire work zone regardless of the length of the section or the work being done. It's necessary to illuminate the entire work zone, White explains, because, one form of work, such as paving, may be taking place in one half of the zone while another, such as concrete repair, is underway in the other half.
Illumination also includes crew members.
Tully management has taken strides to ensure its workers are highly visible. Their hard hats also have reflectors on them. And to help nighttime motorists navigate better through the work zone, Tully crews painted a yellow stripe along the bottom of the mobile barriers. When it's time to dismantle the nighttime work zone each morning, Tully crew members move the barriers and open the lanes for traffic and for daytime work, which usually involves single-lane closures and barriers to protect shoulder workers. During the day, flaggers with slow and stop paddles are an important part of day construction.
