What's up with the Nalley Valley I-5/SR16 Interchange Project?

The construction on I-5/SR16 Westbound will be completed in 2011. After completion of this phase, the next phase - Eastbound - will begin and is proposed to be completed in 2013. The HOV project is planned to begin in 2020 and be completed in 2022.

There are a couple more images I will be posting soon.

Thanks to Claudia Cornish of WADOT for the information!
