Highway Construction Zones and Worker Safety
Roadways with limited shoulders near Interstate 64 and Green Mount Road can restrict responder access and increase risks for workers. When incidents occur in O’Fallon, responders often establish safety buffers to protect people working close to active traffic.
Construction zones typically include changing traffic patterns, reduced speeds, and lane shifts. Drivers approaching these areas may have less space to maneuver, especially when large vehicles such as semi-trucks are present.
Workers operating near travel lanes depend on drivers to slow down and remain alert. Maintaining safe speeds and paying attention to work zone signs can help reduce the chance of crashes in these environments.
