As one of the fastest growing counties in the state and nation, Collin County is making infrastructural enhancements to accommodate the increasing population and road traffic. According to the North Central Texas Council of Governments, the population of Collin County grew to 791,633 by early 2010, signaling a phenomenal 61-percent increase since the 2000 Census. As the County continues to grow, an increasing number of local residents will travel to employment sites within Collin County which will place a great burden on our existing transportation system. Consequently, a cooperative and comprehensive solution to alleviate the existing and projected mobility problems is a constant work-in-progress for the County Commissioners.

Over the last few years, several major projects have been initiated by various entities, including the Texas Department of Transportation (TxDOT), the North Texas Tollway Authority (NTTA) and the Dallas Area Rapid Transit (DART). Many projects are currently underway while others are still in the planning stages. The following is a list of projects which are considered to be among the most important:

Mobility Plan
North Dallas Tollway Extension
Collin County Thoroughfare Plan
Collin County Outer Loop
FM 545 Alignment Study
County Road Paving Program

Northeast Texas Rural Rail District
2007 Transportation Bond Projects
Regional Toll Revenue Projects
Collin County Intermodal Hub Study
