Improvements for State Highway (SH) 183 from SH 121 to I-35E, as well as portions of Loop 12 and SH 114 include obtaining right-of-way, reconstructing portions of frontage roads, reconstructing portions of mainlanes and constructing one managed toll lane in each direction in some locations.
This project is developed under a Comprehensive Development Agreement (CDA), which provided an innovative method for development, finance and maintenance.
- SH 183 from SH 121 to I-35E: 14.8 miles
- SH 114 from International Parkway to SH 183: 10.5 miles
- Loop 12 from SH 183 to I-35E: 2.5 miles
Purpose and Need
SH 183 has served North Texas’ growing transportation needs since the 1940s. The current roadway dates back to 1959 and has remained relatively unchanged since 1973 when an additional mainlane in each direction was added. Today, the highway serves as a primary artery between Dallas and Fort Worth but it and the surrounding roadways, can no longer adequately meet the demand.
