I was wondering why the speed limit is only 40 MPH on Dallas Parkway in both the north and south bound directions between Stonebrook and Main St. It is 50 MPH from SH-121 to Stonebrook and there's a lot more going on in the 50 MPH areas than there is in the 40 MPH area. What is the criteria for determining speed limits?

Dallas Parkway is posted at 45mph from SH 121 to Warren. From Warren to Stonebrook, it is posted at 50mph. From Stonebrook to Main it is posted at 40mph. From Main to US 380, the limit is posted at 45mph.

The section from Stonebrook to Main was originally posted at 50mph. However, when the DNT construction started, there were crashes that occurred as a result of speed in that section. Due to those crashes, the speed limit was lowered to 40mph. This lowering is allowed through a TxDOT workzone detail sheet that we use for evaluating speed limits in construction zones. Once the DNT main lanes are opened and all lane widths in the section return to normal, we will change the speed limit back to 50mph.
