Reconstruction of the bridge on Stonebridge Drive started in early March in order to make improvements to the bridge’s deck, sidewalks, railing and foundation supports. Construction must be substantially complete by Sept. 30, meaning the road is open to traffic, according to a contract between the city of McKinney and construction company Iowa Bridge & Culvert. The city predicts the bridge will remain closed until October, said Nick Ataie, capital improvements manager for the city of McKinney’s development services, in an email. Long-term closures will remain in place until the city determines the bridge is safe to reopen to traffic, according to Ataie. “Drivers should continue to plan for the signed detour route and allow additional time for their commutes while traveling in this area,” Ataie said. “... We understand that this project creates an inconvenience for local traffic, and it was determined during the design process that the duration, cost and safety risks of the project could be significantly reduced by providing a complete closure of the bridge during construction." The bridge’s westbound lane is currently under construction. Eldorado Parkway serves as the primary detour to Custer Road and Stonebridge north of Eldorado. In addition, businesses along Stonebridge east of Custer remain accessible.
