Upcoming Work
Diverging Diamond Interchange (DDI) Traffic Alignment
Oct. 16-19 There will be a full weekend closure of McCaslin Boulevard over US 36 .
This closure is necessary to align traffic into the new Diverging Diamond Interchange (DDI) configuration. The full closure will be in place from 9 p.m., Friday, Oct. 16 through 5:30 a.m., Monday, Oct. 19. Access over US 36 on McCaslin Boulevard will not be allowed. All eastbound and westbound US 36 on- and off-ramps to McCaslin Boulevard will remain open with right turn access only. Left turns and through movements from the ramps to access McCaslin Boulevard will be closed during the bridge closure. Detours will be in place to guide the traveling public, but alternate routes are advised. To view the detour routes and closure points, go to us36expresslanes.com.
The traveling public will need to be extra cautious when driving on the new DDI for the first time starting on Monday, Oct. 19. To view an instructional video on navigating the new DDI, click here. The DDI alignment requires motorist to travel on left side of the road to cross the bridge, which allows free movements on and off of McCaslin Boulevard from US 36 with yield movements. New signage will be in place.
Once the weekend activities have been completed, there will be miscellaneous construction activities through December at the interchange including ramp paving, sidewalk and median construction and the bridge arch installation. The DDI is scheduled for completion by the end of the year.
