The construction limits are approximately just north of SW 8 Street to NW 25 Street on S.R.826; just east of NW 87 Avenue to NW 57 Avenue on S.R. 836. Capacity improvements include the reconstruction and wideningalong both S.R. 826 and S.R. 836, the construction of a four-level interchange as well as the reconstruction/modifications of the Flagler Street/ S.R. 826 and the Milam Dairy Road/NW 72 Avenue/S.R. 836 interchanges.

• Construction of new connections between S.R. 826 and S.R. 836 in all directions allowing drivers direct access and reducing travel times
   
• Construction of a new direct connection from northbound S.R. 826 to westbound S.R. 836

• Installation of Intelligent Transportation Systems (ITS) cameras and sensors allowing for real-time traffic updates, as well as assisting in the rapid deployment of first responders and Road Rangers to clear disabled and accident vehicles from travel lanes
   
• Reconstruction of NW 11 Street from NW 72 Avenue with a connection to Milam Dairy Road
   
• Installation of new signalization, lighting and landscaping
   
• Reconstruction of NW 12 Street beneath S.R. 826
