The reconstruction on I-35W from I-820 to I-30 is referred to as "Segment 3A".
The mandatory scope schematics for the I35 reconstruction are posted at http://www.txdot.gov/government/partnerships/current-cda/north-tarrant-express/interim-project.html.
Please note that the documents at that website reflect the original schematic design; they do not reflect the design changes that have been implemented and were recently presented to ONA. A PDF copy of that presentation (showing the improvements to the design) is posted below.
