The LBJ Express Project will be performing bridge demolition on the I-635 auxiliary lanes that run over the Dallas North Tollway this weekend! The demolition will occur in 5 Steps with each step representing a designated area of demolition. (Areas of demolition shown in the map as a red box with lines through it). The four loops will be closed for the duration of this work over the weekend.

For safety purposes the DNT SB will be directed to exit at Alpha Road and detour through the Inwood box over LBJ. Additionally, 1 through lane will be open on NB DNT.  Step 1 traffic control will be implemented at 9pm on Friday night and the demolition of the outer bridges will begin at 10pm.  The configuration shown to the right will be in place until approximately 12pm on Saturday.
