Be alert to lane changes and pavement resurfacing on the Interstate 25 overpass bridges above Walsh Drive, according to the Wyoming Department of Transportation.

On Friday, crews will switch traffic in the southbound lanes, closing the passing lane and reopening the driving -- right -- lane to work on the passing lane.

While the driving lane will be open, the southbound on-ramp from East Yellowstone Highway will remain closed.

To access southbound I-25 from East Yellowstone Highway, or the Beverly Street/Bryan Stock Trail area, use the McKinley Street on-ramp or the Curtis Street/Wyoming Boulevard interchange.

On Monday crews will begin working on the northbound driving lane.

This will require closing the northbound on-ramp at the Curtis Street/Wyoming Boulevard interchange. The on-ramp will remain closed until all work is completed in the northbound lanes.

To access I-25 northbound from this area, use the Beverly Street/Bryan Stock Trail on-ramp.

The speed limit through the work zone is set at 45 mph.

WYDOT does not have a timeline for the completion of this project.
