Existing Conditions• Railroad (U.P.R.R.) crossing Capstone Drive• The existing Right-of-Way is 100 feet wide for Barron Rd and 80 feet wide for Capstone Dr
• Intersections are offset at Wellborn Rd (FM 2154)

Purpose and Need• Insufficient distance between the Barron and Capstone intersections with Wellborn Rd (FM 2154)
• Intersections too close for two traffic signals• Discontinuous route in east-west direction• Intersection safety issue/accident history • Traffic projected to increase

Project Goals1. Re-align either Barron Road or Capstone
Drive into a single signalized intersection with Wellborn Road
2. Widen Barron Road to accommodate future traffic volumes and multiple modes of travel
3. Widen the at-grade railroad crossing for the ultimate roadway cross section

Summary of Recommendations1. Re-align Capstone Drive using Alternative 1 or 22. Install traffic signal at the intersection of
Wellborn Rd 3. Widen Barron Rd to four-lane divided roadway4. Widen Wellborn for right & left turns at new
intersection5. Construct railroad crossing for potential future
quiet zone
