ITD shifts U.S. 20 traffic to new overpass bridge as South St. Anthony interchange nears completion

ST. ANTHONY, Idaho (KIFI) — Beginning this week, the Idaho Transportation Department (ITD) is shifting traffic on U.S. 20 onto the new overpass bridge at the South St. Anthony Exit 334 as the new interchange project nears completion.
Previously, drivers were routed onto the ramps while the bridge was being built, with a reduced speed limit of 35 mph. Now, traffic will flow on the main U.S. 20 lanes, though a reduced work zone speed will still be in effect.
During this shift, the South St. Anthony ramps will remain closed so crews can finish work on 400 North underneath U.S. 20. Workers and equipment will still be present on site, so ITD is urging drivers to stay aware and be cautious.
ITD anticipates the project will wrap up later this summer. Once complete, the ramps and turning movements onto 400 North will be open.
