Benjamin Franklin once said, "Being ignorant is not so much a shame, as being unwilling to learn." There have been lots of lessons in public works in 2014 and we've tried to absorb them all. Here's a look at some of the things the year has taught us.

1. Great work can still impress. Here's a look at some of the project highlights from this year.

2. Infrastructure is big news, especially when something goes wrong.water main break in Los Angeles, a water crisis in Ohio, and a report on CBS's "60 Minutes" all caught national attention.

3. The old dog CAN learn some new tricks. From pilot projects to make roads safer to money-saving solar, new technology is allowing the industry to evolve. What will it look like a year from now?

4. Sometimes it pays to think small. We were reminded of this in September, when we learned how a hand tool made it possible for one person to clean out an entire culvert.

5. Public Works jobs don't make millionaires, but the money is coming back. More than 1,500 respondents completed our annual salary survey and 61% said their salary had increased in the past 12 months.There's good news for civil engineers too.
