AT&T dialed in the final pieces of work related to a resurfacing of Ninth Street largely completed five months ago, as the telecommunications company wraps up its responsibilities on various city repaving jobs.

A contractor hired by AT&T has been out this week, adjusting covers for AT&T valves so that the metal plates match the level of each stretch of new pavement, said Mark Thiel, assistant director of public works for the city of Lawrence.

Workers also are installing new concrete collars around such covers, so that such adjustments will no longer be necessary the next time the city resurfaces the streets, he said.

AT&T is responsible for making the adjustments to its valve covers — which provide access to their underground lines and equipment — and also for financing all the work.

AT&T had a total of seven valves to adjust on a variety of repaving jobs, including one project between Ousdahl Road and Barker Avenue along 23rd Street.

“That’s why they waited to do them until now,” Thiel said. “It’s more economical for them to hire a contractor at one time to do them all, instead of one at a time.”

AT&T’s crew adjusted valves along Ninth Street, a repaving project that resurfaced the road between Iowa and Tennessee streets. The work caused temporary traffic delays, and a center turn lane on Ninth at Avalon Road remains closed until Friday, so that concrete has a chance to cure.

Adjustments to valve covers for city services — such as sewer lines, drainage pipes and water lines — were completed along Ninth soon after the street received its new pavement this past summer, Thiel said. The repaving’s contractor, R.D. Johnson, handled the adjustments as part of its $678,211 project, which also included adding the center turn lane at Avalon.

Before the repaving, the stretch of Ninth carried an average of 17,000 vehicles per day.
