ODOT D12 CUY-271-14.49

Mainline Bridge over Wilson Mills Road

Osborn Engineering provided engineering services for the replacement of twin, 4-span structures along I-271 (local lanes). The project included the design of new 2- span, semi-integral steel beam structures over Wilson Mills. New center piers, including drilled shaft foundations, were designed to carry the increased loading resulting from the reduction in spans.

Additional design tasks included new approach slabs, bearings and parapets. Four lanes of traffic in each direction were maintained on I-271 by utilizing crossovers and the existing express lane bridges. Load rating using AASHTOWare-Bridge Rating was also performed.
