This weekend navigating the ramps between Interstate 635 and the Dallas Tollway will be a little tricky due to some lane closures slated to occur intermittently Friday-Sunday.

While ramps are closed, LBJ Express crews will be installing concrete beams atop recently constructed bridge columns along the Tollway. The beams will serve as the foundation for the final phase of TEXpress Lanes, scheduled to open December 2015.

Traffic will be detoured to Inwood and Dallas Parkway Friday and Saturday night to maneuver around the closures. Work should be complete by noon on Sunday, June 29, however closures will be lifted if work is completed earlier.

Check out the full list of the closures below:
