Nighttime maintenance on I-380 in Cedar Rapids begins

Work will take place nightly between 8 p.m. and 6 a.m. on Sunday, May 31, and Monday, June 1, weather permitting.

Workers will use a crash attenuator during the project. The attenuator is a trailer towed behind a DOT truck that acts as a moving buffer between traffic and workers. It has flashing lights and reflective panels to help drivers see it.

If a vehicle approaches the attenuator too fast or too close, the operator will sound a loud warning alarm to alert the driver. The Iowa DOT will use attenuators at night. The alarm is not constant — it sounds only when needed to prevent a crash. Nearby residents may hear it.

Safe driving in the work zone

Drivers in the work zone should:

• Slow down and obey posted speed limits
• Stay alert and keep space between vehicles
• Wear seat belts

Traffic fines for moving violations are at least double in work zones.
