Improvements/extension
At the Tollway's southern end, near downtown, the agency has rebuilt the road around the main toll plaza and added ramps at Oak Lawn Avenue. This project, started in 2006, ended in late fall 2008. On the southern sector of the tollway, the agency plans to spend about US$43 million to add an entrance and exit at Oak Lawn and rebuild most of the tollway surface from the Interstate 35E ramps to Lemmon Avenue. The tollway authority has completely rebuilt the aging toll plaza, adding a third TollTag express lane in each direction. This work coincides with major projects by the city of Dallas to rebuild part of Oak Lawn under the tollway, and by Dallas Area Rapid Transit (DART) to build a rail line along nearby Harry Hines Boulevard.
The North Texas Tollway Authority started work in January 2006 at seven north Dallas locations to improve ramps and add merging lanes. The project will cost US$14 million. Northbound projects included adding acceleration or auxiliary lanes between Keller Springs and Trinity Mills roads and between Alpha and Spring Valley roads. Southbound projects include adding outside lane pavement at the President George Bush Turnpike exit; between the Bush Turnpike entrance ramp and Frankford Road; between the Frankford entrance ramp and Sojourn Drive; around the Keller Springs exit at the main lane toll plaza; and between the Keller Springs toll plaza and Spring Valley. The projects will noticeably lengthen many shorter merging lanes, including one at Trinity Mills where vehicles must merge quickly after driving around a curve.
Having completed the third extension north, NTTA plans to further extend Dallas Parkway from US 380 to the Grayson County line. It is planned to be a 13.5-mile (21.7 km) extension. A two-lane county road was upgraded from US 380 to Farm to Market Road 428 in Celina and is currently open to traffic. North of FM 428, a route has not been established, but NTTA has approved hiring of a corridor manager for this project.

Famous quotes containing the words improvements and/or extension:
“A country whose buildings are of wood, can never increase in its improvements to any considerable degree.... Whereas when buildings are of durable materials, every new edifice is an actual and permanent acquisition to the state, adding to its value as well as to its ornament.”
—Thomas Jefferson (1743–1826)
“The motive of science was the extension of man, on all sides, into Nature, till his hands should touch the stars, his eyes see through the earth, his ears understand the language of beast and bird, and the sense of the wind; and, through his sympathy, heaven and earth should talk with him. But that is not our science.”
—Ralph Waldo Emerson (1803–1882)
