TxDOT I-30 EXPANSION PROJECT UPDATES
(Click the image below to go to their website.)

 

PROJECT DETAILS/OVERVIEW

The I-30 expansion project will widen I-30 from Bass Pro Dr. to the Hunt County Line and add continuous frontage roads, including across Lake Ray Hubbard. The current configuration is inadequate to handle traffic congestion and population growth, and results in bottlenecks and road closures when there is an incident on the lake bridge. Adding separate frontage road bridges and expanding the mainlanes means traffic can continue to cross the lake if an incident has closed or limited general purpose lanes.
