Trinity Parkway and S.M. Wright


 

Trinity Parkway

The Trinity Parkway was identified in the 1998 Trinity Parkway Corridor Major Transportation Investment Study, prepared by TxDOT, as a reliever route and much needed addition to Dallas' transportation system. It was originally envisioned as a 6/4 lane toll road, extending 8.5 miles, from SH 183/IH-35 in the north, down to US 175 in the south. It will have a capacity of 100,000 vehicles per day.

The Trinity Parkway Record of Decision 2015 has been received form the Federal Highway Administration regarding the development of the preferred Alternative 3C alignment for the Trinity Parkway on April 2, 2015.  The U.S. Army Corps of Engineers signed the Record of Decision (ROD) from the Modified Dallas Floodway Project Record of Decision April 2015. These key federal approvals facilitate the start of construction for amenities in the Dallas Floodway such as phased lakes.

Currently, a Technical Advisory Committee established by Dallas Mayor Mike Rawlings is exploring tweny ideas for the Trinity Parkway Project from an earlier deisgn report that was led by urban deisgner Larry Beasley.  This "Dream Team" produced the Trinity Parkway Charrette Report which was also taken to the public through a series of public meetings in May and June of 2015.  The Technical Advisory Committee is taking all the findings into consideration on behalf of the Trinity Parkway and evaluating their feasibility and potential impacts on the project.  Below is a condensed timeline regarding the Trinity Parkway and "Dream Team" Report and ongoing project progress.

  ​​S. M. Wright

Plans to transform S.M. Wright Freeway into a low-speed, landscaped, pedestrian-friendly boulevard are underway by the City and the Texas Department of Transportation (TxDOT). To alleviate a 90 degree angle in US 175 and IH 45, the following changes will be made to this dangerous stretch of the freeway:

  • Add direct connecting ramps between US 175 (CF Hawn Freeway) & IH 45
  • Improve IH 45 capacity to facilitate new direct connecting CF Hawn ramps
  • Provide access between CF Hawn & SM Wright through a grade separated interchange
  • Convert SM Wright to a low speed, signalized, pedestrian-friendly, landscaped arterial
  • Spacing provided to allow proposed Trinity Parkway connection and extension

Concept for the lower speed neighborhood boulevard with the view to the north on Pennsylvania Avenue.

The planned ramps connecting CF Hawn to IH-45 will divert commuter traffic off S. M. Wright and reduce its 107,000 daily vehicles to about 40,000: a reduction that allows TxDOT to convert the existing elevated, 10-lane high speed S. M. Wright Freeway to a 6-lane low-speed, at grade and signalized boulevard without a bridge. Additional exciting plans will allow installation of pedestrian trails, gateway monuments and attractive landscape features.

2017 TWM Project Updates

The S. M. Wright Project allows room for the future Trinity Parkway improvements. TxDOT continues to work alongside the NTTA, City of Dallas, the U.S. Army Corps of Engineers, NCTCOG, FHWA, and USEPA on many improvements in the area.
