Starting at 9 p.m. Friday, westbound Interstate 270 will be closed from the Interstate 55/70/270 interchange to Illinois 3.
A posted detour will direct traffic to take westbound Interstate 55/70 to northbound Interstate 255 to westbound New Poag Road to southbound Illinois 3 to access westbound Interstate 270.
Westbound traffic will not be able to travel on Interstate 270, west of the Interstate 55/70/270 interchange.
