Columbia’s busy Clark lane will reopen Friday at Hanover Boulevard, after being closed for about two months for crews to build a roundabout.

Improve I-70 program director Eric Kopinski tells 939 the Eagle that they’ll open Clark lane Friday afternoon. We don’t have an approximate time yet.

Crews have been building a roundabout and constructing new pavement in the area. The work is part of the $405-million project to rebuild and expand I-70 from Columbia to Kingdom City.
