ST. LOUIS, Mo. — Drivers traveling between St. Charles County and the rest of the metropolitan area face several significant construction restrictions this week, including a Discovery Bridge traffic shift and continuing lane closures on Interstate 170.

MoDOT’s October 29–November 4 work-zone report says two westbound Route 370 lanes have been moved onto the eastbound Discovery Bridge over the Missouri River. Two eastbound lanes are shifted right, with a temporary barrier separating opposing traffic.

On I-170, one lane in each direction is closed between Natural Bridge Road and St. Charles Rock Road. That restriction is scheduled to continue into late spring 2027.

The report also lists the ramp connecting westbound I-64 to eastbound I-70 as closed through mid-November. At David Hoekel Parkway, westbound I-70 entrance and exit ramps remain closed through late November.

The restrictions affect several routes used for airport trips and regional commuting. MoDOT advises checking current traffic conditions before leaving, allowing extra time and following posted work-zone speeds. Construction schedules remain weather-dependent and can change.
