CEDAR RAPIDS (KWWL) - The cleanup from recent snow is still underway. Not just on roads, but on markings like stop signs and traffic signals.

Diana Langguth says she's noticed how snow can pile on during a storm.

"Mostly the (stop) lights is what I see a lot of snow on," said Langguth.

She never thought about who cleaned them up.

"I don't know if I just thought they cleaned themselves or what," said Langguth.

That is how they worked in the past. Cities used to rely on the light bulbs in the stoplights melting the snow but the new LED light bulbs don't do that as well.

"They were warmer so they were self-cleaning," said Calvin Brown, Traffic Signal Technician for the City of Cedar Rapids.

Now, cities have to clear blocked signals manually.

"We go up in a bucket truck and physically clean it out with our hands or a small broom," said Brown. "Sometimes we use a telescoping rod that we tape a stiff bristle brush to so we don't need a lift truck then."

They rely on people reporting blocked signals to make sure they get cleared.

As for signs on the road, street crews look out for those while they're working and try to get them clear, too.
