Interstate 35 motorists will encounter lane closures and possibly traffic backups through July 11 between Northfield and Elko while crews complete a bridge painting project, according to the Minnesota Department of Transportation.

The project began this week to paint the bridge, between exit 76 and exit 69 on I-35.

Lane closures in both directions will alternate as the crews paint the bridge.

According to a press release, because of traffic volumes on I-35, traffic backups are likely, especially on weekends. Motorists can decrease traffic backup dangers and move more efficiently through a merger point by using both lanes of traffic while approaching the merge. To learn more, go to MnDOT’s website on the “zipper merge” www.dot.state.mn.us/zippermerge/

The lane closures are necessary for the safety of motorists as well as the painting crews to safely complete the project and provide their equipment with the space to do the work.

MnDOT urges motorists to always be attentive, drive with caution, slow down in work zones and never enter a road blocked with barriers or cones.
