The construction crew is making progress on a huge project to replace the Highway 169 bridges over Bird Creek between Tulsa and Owasso.
The progress may be difficult to see from the ground, but from Osage SkyNews 6 HD it's clear.
The Oklahoma Department of Transportation is actually replacing eight bridges in the area, four in the northbound lanes and four in the southbound lanes. The $45-million project will also widen the highway to three lanes in each direction.
The project is only a week old, but from the air you can see the construction crew is building a detour for the northbound lanes that will bypass all four sets of bridges to be replaced. They include the bridges over 56th Street North, Bird Creek, the Bird Creek overflow and 66th Street North.
As a result, the crew closed the northbound on-ramp from 56th Street North.
The two truss bridges over Bird Creek were built in 1960. The other bridges being replaced were all built at the same time.
The replacement project is scheduled to be finished in the spring of 2017.
