"Spaghetti Bowl" filling up
The Chisholm Trail Parkway/Interstate 20/State Highway 183 interchange consists of numerous bridges that will eventually become the CTP direct-connector ramps, main lanes and frontage road system. With so many bridges, the interchange is often referred to as the "Spaghetti Bowl." To make the transition from one roadway to another seamlessly, the following connections are being constructed between the three thoroughfares:
* Eastbound I-20 to northbound CTP
* Westbound I-20 to southbound CTP
* Southbound CTP to westbound I-20
* Northbound CTP to eastbound I-20
* Arborlawn Drive to southbound CTP
* Northbound CTP to Arborlawn Drive
Texas Department of Transportation crews also have worked in this area since spring 2010, focusing on local access improvements, including the construction of a sound mitigation wall near Country Day School and the lowering of the SH 183 main lanes. As the SH 183 main lanes are lowered, the CTP is being constructed overhead, with the tallest structure standing 105 feet from ground level.
