The southbound side of the highway is congested between Exits 18 and 13 — a distance of about 5 miles — because of road work. The construction zone itself is between Exits 14 and 13. The right lane is closed in that section, squeezing traffic into the other lanes.
The state Department of Transportation expects that the road work will end for the day by 3 p.m., so it shouldn’t impact the evening rush hour. Check back for updates.
