NORTH ST. LOUIS COUNTY - MoDOT crews will close one eastbound and one westbound lane of I-270 from Route H (Riverview) to just east of Lilac starting at 6 a.m. Saturday, June 27 through 5 a.m. Monday, June 29.

The closures will allow crews to switch eastbound I-270 lanes to the north, in preparation of opening the Route H entrance ramp to westbound I-270 and closing the eastbound I-270 exit ramp to Route H.

Starting at 6 a.m. Saturday, June 27, crews will close the eastbound I-270 exit ramp to Route H to construct a new ramp. The ramp is expected to be closed for two months.

The Route H entrance ramp to westbound I-270 has been closed for several months and will reopen by 5 a.m. Monday, June 29.

The work is part of the I-270/Route H upgrades project, which is expected to be completed by the end of this year.

All work is weather dependent.
