The main runway at Brownwood Regional Airport has been turned into a construction zone.

Tuesday afternoon, a succession of large trucks carrying hot mix from Vulcan Materials in Brownwood rumbled through the entrance gate and onto the ramp, then drove across taxiways until they reached the airport's main runway.

There, the trucks lined up with numerous Duininck Brothers construction vehicles and heavy equipment that lined the runway's length.

The construction is part of a $2.8 million runway improvement project approved last year by the Texas Department of Transportation's Texas Transportation Commission. Improvements including resurfacing the runway and changes to lighting.

As part of the project, the runway's width is actually being reduced from 150 feet to 100 feet, which will make the runway less expensive to maintain, airport officials said.

"It's a pretty interesting operation. It really is," project inspector Kevin Rust said as heavy equipment rumbled and vibrated.

Rust, of Stephenville, is retired from TxDOT and was hired as the inspector. "God has blessed me with this job. I'm so thankful to be able to have that," Rust said.

Airport employees were busy with a smaller project of their own: towing a disabled Cessna from the airport's secondary runway to a hangar for a repair. The plane had "lost a brake line," airport forewoman Jennetta Toeppich said.

Airport manager Bobby Burks said the runway construction project is "coming right along now that we've got the weather."
