Probably the 'News' section of the Barclay Group's website will have an update in the near future. From driving down 466A today, it appears the initial excavation work that began last August has finally ended. The lines and arrows are painted in the turn lanes and today only finishing touches were being done, such as watering the dirt off the highway. There does appear to be one small backhole digging a hole in the median closest to BV, that appears to be for a street light.
Here's a link to the developer's website:
