PLANT CITY – The city plans to hire a contractor to rebuild about 75 percent of Timberlane Drive because the road's base is crumbling,
City Engineer Brett Gocka said. A cost estimate for rebuilding Timberlane, which is the main road through Walden Lake, hasn't been determined. The city hired an engineering firm to look at the road because it was cracking and developing an alarming number of potholes.
Madrid Engineering determined that the sand-based cement that made up the foundation for the road was deteriorating and undermining the asphalt.
Rebuilding three-fourths of the 2.9-mile road was the only solution, Gocka said. All the portions of Timberlane in need of work are west of Alexander Street, he said.
A milling machine will be brought in to grind up the asphalt and the sand-based cement and rebuild the base. The crews will then add new asphalt.
The road through the city's largest development was last resurfaced in 2004, and the city expected the asphalt to last at least 20 years.
Gocka said the portion that is crumbling dates back to when the road was built at least 30 years ago.
“It's a long-term deterioration,” he said.
