If you’ve spent any time on 94 driving between the Twin Cities recently, it’s hard to miss the developments at Allianz Field that are beginning to give a clear view of what Minnesota United’s soccer-specific stadium is going to look like when completed. Recently, Mortenson began installing the PTFE screen that will give Allianz Field its signature look and with the fifth of 10 panels going up on Wednesday, that process is about half done. The goal is for the membrane to mimic the qualities of water in Minnesota’s lakes — sparkling and bright in the sun yet transparent and refractive in the shade.
