Are there plans to expand the four lane stretch between the I-35E/35W split north of hillsboro to the 6 lane expanded concrete section some 7 miles away?

Bids were received in May with the lowest bid $133 million. So work should be underway soon.

I reviewed the plans online when they became available a few months ago. The design is similar to adjacent section, 3x3 concrete with full shoulders and a central concrete barrier. The median will be paved, so there will no longer be a median.
