Motorists in northeast Columbia who use Clark lane will have to make changes in their daily commute, starting Monday.
State transportation officials say Millstone Weber and other contractors will close Clark lane at Hanover Boulevard at about 6 am on Monday, so crews can build a roundabout there and construct new pavement. That intersection will be closed for about 60 days, and the Missouri Department of Transportation (MoDOT) expects the roundabout to open to all traffic in October.

This work is part of MoDOT’s $405-million project to rebuild and expand I-70 between Columbia and Kingdom City.
