The project to replace the Highway 169 bridges over Bird Creek just south of Owasso has reached a milestone.
A crew spent the weekend moving the barricades so that northbound traffic is now traveling on the brand new bridges.
The Oklahoma Transportation Commission approved the $45,500,000 contract in April of 2015.
The project included replacing the old steel truss bridges over Bird Creek, which were built in 1960, as well as concrete bridges just to the north and over 56th Street North just to the south of the creek.
Both north and southbound traffic has been using the newly-constructed southbound bridges for several months. But this weekend, northbound traffic has been moved to the new northbound bridges. The new bridges carry three lanes of traffic in each direction.
Moving northbound traffic onto the new northbound bridges is a major step in the project, but it won't be officially finished for a few months yet.
