If curious, we need it not be raining and it's supposed to rain tonight and tomorrow night so doing it during the dry window tomorrow morning is our best chance and we're going to take it. We'll keep you updated on when work is complete!

For those curious - the lane closure is for crews working on future support columns for the new Roanoke lid in between EB and WB SR 520. The lane closure gives crews and drivers the space needed to complete the work safely.

The image shows a highway construction scene under a clear blue sky. In the foreground, there is a large crane with a blue boom placed next to a highway off-ramp. The construction site is surrounded by orange safety barriers and cones, and there is a dirt mound on the right side with workers and a cement truck. In the background, a multi-lane overpass extends horizontally across the image, with several vehicles in motion. A dense line of green trees is visible behind the overpass on the left. Street lamps and power lines run along the roadways.
