Drivers on the Dallas North Tollway can expect overnight closures through Wednesday.
The LBJ Express team will be setting down beams along Interstate 635 and the Dallas North Tollway through the beginning of April.
The work will result in full closures of the tollway over LBJ through Wednesday morning.
"There will be delays. But be careful; stay off your phones," LBJ Express Project spokeswoman Heather Delapp said. "Safety is the top priority for the project, so we want to make sure that they read the signs and message boards that are out and just allow that extra time for construction."
