Bearss Avenue, a major commuter route closed last week so workers could replace a railroad crossing, is open again.
The work was completed at 8 p.m. Tuesday, a day and a half early.
"The guys really busted their butts to get it open," said Steve Valdez, community relations manager for Hillsborough County.
That meant a section of Bearss east of Nebraska Avenue was closed for five days instead of seven.
During the closure, CSX Transportation Inc. replaced its tracks and a section of rubber between them, Valdez said. The 13-year-old equipment had been worn down by up to 60,000 vehicles a day passing over it.
Valdez said similar wear is affecting lots of infrastructure that was built about a decade ago, and such repairs will be common around the county.
"It's a cyclical thing and it's coming up at us," he said.
