The temporary bridge over Stillwater River in Old Town will be closed for several nights next week.
That will allow crews to winterize the temporary Llewellyn Estes Bridge that carries Stillwater Avenue over the eponymous river, according to the Maine Department of Transportation.
The nighttime closures will be in place from 8 p.m. to 5 a.m. Sept. 27 to Oct. 2.
Crews will be realigning the pedestrian curb, insulating deck panels to the girders, tightening deck anchors, and more.
Drivers will be detoured through Orono on College Avenue and Bennoch Road to get around the construction site.
That comes as work continues on building a new Llewellyn Estes Bridge, a portion of which collapsed on the afternoon of Aug. 14, injuring one person.
Inspectors found no collateral damage to the temporary bridge from the collapse.
The bridge is being constructed by Woolwich-based Reed and Reed Inc. using Winterport-based engineering firm Basalt International’s fiber-reinforced polymer and girders designed by the University of Maine’s Advance Structures and Composites Center.
Basalt International has heralded the polymer, which was developed in Maine, as a “miracle material.” The Advance Structures and Composites Center’s girders, known as GBeams, have been used for two new bridges in Hampden and others across the country.
Few details have emerged about what may have caused the collapse.
The Maine Department of Transportation is working with the Federal Highway Administration to piece together what happened to the $28 million bridge.
It’s unclear how the collapse will affect the bridge’s price tag and the timeline for completing construction.
