If you're thinking about selling your used construction equipment or agriculture equipment, you may be wondering how to figure out your item's worth. If you auction off your used tractors, mixers and other equipment with IronPlanet, the online auction site can help determine the financial details of your goods.

The U.S. economy has been slowly recovering since the recession that hit in late 2007, and the construction industry has been experiencing the gradual improvements, which has in turn helped local economies across the nation. In fact, the U.S. Labor Department recently announced their March employment data was underestimated by about 386,000 jobs, according to the Los Angeles Times. Nearly 23 percent (85,000) of these jobs were in the construction sector.

In addition to offering a wide selection of used construction equipment and agriculture equipment, IronPlanet also ensures that buyers know what they're getting. Since the auctions take place online, buyers cannot personally examine the items they're interested in, which is where IronClad Assurance comes in.

In a few weeks, the current farm bill is set to expire, but since many political officials are busy working on campaigns for the upcoming elections, the renewal of this legislation will be pushed back, causing worry among the agriculture industry. On Sept. 20, Speaker of the House John Boehner announced the vote for the new farm bill, H.R. 6083, would be delayed until after the November election, according to the Des Moines Register. Boehner explained there is uncertainty whether there are enough votes to pass the bill in the House, even though the Senate passed it in June.

California is planning to revamp its rail system to make way for a new high-speed rail line and improve upon existing tracks throughout the state. According to The Associated Press, the Federal Railroad Administration recently approved the first phase of construction on the Golden State's rail modernization project. Construction equipment will soon become a common sight along a 65-mile corridor from Fresno to Merced, as this is the first section of the planned 800-mile railway system to be built.

Traveling to Wichita, Kan., may be a lot easier soon, as construction is underway for a new $101.5 million terminal in the city's airport.

The Wichita Eagle reports that rain stopped the official groundbreaking ceremony for Air Capital Terminal 3 (ACT 3), but that didn't diminish the hope of what this project may accomplish. The grounds were actually broken a month ago for construction purposes, according to the news provider.

"There’s an old Irish saying, that when there's bad weather on the day of a wedding, the marriage will succeed," Victor White, the city's director of airports, told the news provider. "I hope that holds true for construction projects."

Typically, the only way to get a good look at military fighter jets is to attend an air show, but residents living near the Des Moines International Airport are being treated to regular displays of these aircraft. A construction project currently taking place at the airport resulted in the closure of the runway used by the Iowa Air National Guard's 132nd Fighter Wing, according to the Des Moines Register. The National Guard cannot simply stop training for the project, so flights have been redirected to another runway.

For the past two years, the West Wing of the White House has been strewn with construction equipment, cranes, excavators and trucks. Now, the $86 million project is finished, and The Associated Press reports the building appears as though it had remained untouched. This is because most of the work was done on the inner workings of the wing - replacing water lines, sewers and electrical wiring pipelines as well as updating the heating, air conditioning and fire control systems.

The night before the anniversary of the September 11 terrorist attacks, officials have announced that construction of the National September 11 Museum in New York City will soon resume.

The museum is being built on the site of the attack in Manhattan, which is also the site of the 9/11 Memorial that was completed and opened to the public last year, on the 10th anniversary of the attacks.

The project is intended to repair major issues and update some of the older stations along this busy route.

Boston may be a small city, but it is still growing and building new neighborhoods such as Channel Center. The New England city's Seaport District, also known as the Innovation District, has been undergoing transformations in recent years to make it a more vibrant part of Boston, including the construction of many new business and residential buildings. State Street Corporation is planning to relocate its headquarters from various buildings around the downtown area to the Innovation District once its new home, One Channel Center, is completed, according to the Boston Herald.

Renovations to the Indianola Middle School building in the University District of Columbus, Ohio have been halted.

Farming is often a family business, and many farmers put their kids to work in the fields. Eventually, these children may be asked to drive tractors and operate other agriculture equipment. However, deciding when a child is ready to undertake this responsibility can be difficult. Researchers in Iowa are setting out on a new study using a driving simulator to find a way to assess the driving skills of youngsters who work on farms, according to The Associated Press.
