Rationale for Expansion

• 🗓️ This initial phase is anticipated to be completed by early 2029.

Long-Term Vision and Impact

• 🗺️ Future plans include extending the freeway east of McKinney, looping around McKinney National Airport, and connecting to US 380.
• 💰 The full buildout of the project is estimated to cost nearly a billion dollars.
• 🚗 The expansion aims to improve east-west travel on Spur 399 and alleviate traffic on other major roadways.
