All eastbound and westbound lanes of Interstate 30 through downtown Dallas will close this weekend for major construction as part of the ongoing I-30 Canyon Project.
The Texas Department of Transportation said the full closure will run from 10 p.m. Saturday, Oct. 24, to 5 a.m. Monday, Oct. 26, between the Interstate 35E interchange and the Interstate 45/U.S. Highway 75 interchange. A signed detour will direct drivers to State Highway 366 and Woodall Rodgers Freeway as an alternate east-west route. The Dallas Morning News reported that motorists should still expect congestion and longer travel times during the shutdown.
The work is part of the $888 million I-30 Canyon Project, which is reconstructing and improving the corridor between I-35E and I-45. The project broke ground in March and is expected to finish by 2031. Once complete, the interstate is planned to widen to 12 main lanes from the current six, with longer weaving distances between interchanges to improve safety and traffic flow.
