The Denton County Connections (DCC) project is a collection of intersection and road improvements intended to address the traffic bottlenecks caused by rapid population and industry growth along the I-35 corridor in Denton County. This is a Texas Clear Lanes project. Texas Clear Lanes is a statewide strategic plan to provide congestion relief through non-tolled roads and is focused on the five largest metro areas in Texas.


Increased traffic along the I-35E corridor coupled with regional population growth in Texas has created travel demand that exceeds its current capacity. The existing I-35E facility in Denton County is an essential element of the local and regional transportation system.


The purpose of the collection of projects is to increase capacity and improve safety operations. Bundling these projects will result in economy of scale and achieve the best use of taxpayer dollars.
