(CNN) -- The names on the formal, state-government-erected memorial signs by the sides of Ohio highways are not famous to the outside world.

But once you know the story behind them, you understand completely. You look at those signs and you offer a silent word of thanks.

Usually stretches of highways around the country are named for politicians, or for renowned figures from American history, or perhaps for singing stars or athletes or Hollywood actors who were born in the area.

For the last several years, though, whenever I've been in Ohio I have noticed the highway signs with the unfamiliar names.

Last week I got in touch with the Ohio Department of Transportation to ask about them.

The answer makes you want to pause humbly.

On August 31, 2009, Marine Lance Cpl. David R. Hall, of Elyria, Ohio, was killed in an explosion while serving in Garmsir, Afghanistan. He was 31; he worked at a Ford assembly plant back home before joining the Marines.

In most cases of fallen service members, there is a solemn funeral ceremony when their remains are returned home, and a respectful obituary in the local newspaper. It can feel all too fleeting.

But in Ohio, in recent years, there has been an effort to do more.

Which is why the Ohio General Assembly authorized that a stretch of State Route 2 in Lorain County -- David Hall's home county -- be named, now and forever, to honor him.

"After the General Assembly votes to name a portion of a highway, we manufacture the signs and put them up at the designated places," said Steve Faulkner, a spokesman for the Ohio Department of Transportation. He said that two signs are usually erected, each facing a different direction, so that people in cars on either side of the highway will see the honoree's name.
