Ramp and lane closures are scheduled around Route 390 this weekend to make room for bridge beam placement in northwest suburban Itasca.

One eastbound lane of Route 390 will close at 9 p.m. Saturday between Meacham Road and I-290, according to a statement from the Illinois Tollway. A second lane will close at 11 p.m.

The ramp connecting Meacham to eastbound Route 390 will close at 1 a.m. Sunday, the tollway said. The ramp will reopen by 7 a.m. Sunday, and all lanes will reopen by 10 a.m.

Posted detours will redirect traffic via the eastbound frontage road to Rohlwing Road, and north along Biesterfield Road to reach the I-290 interchange, according to the tollway. Traffic will be directed onto eastbound I-290 to reach Route 390.

The closures are needed to facilitate beam placement for the construction of a new Rohlwing Road bridge to Route 390, the tollway said.
