A faster speed limit may be in the works for Chisholm Trail Parkway between Arborlawn Drive and Interstate 30. The Fort Worth City Council voted to amend an agreement the city has with the North Texas Tollway Authority (NTTA) and the Texas Department of Transportation, which requires the speed limit to be 50 mph. NTTA plans to conduct a speed study and consider increasing the speed limit. – Samantha Calimbahin, FWBÂ
