I-70 Bridge to Detour Drivers During Summer and Next Year
For 12 months starting in November and for several weekends this summer, construction on Interstate 70's Blanchette Bridge over the Missouri River, between St. Louis and St. Charles, Mo., at mile marker 230, will detour westbound I-70 traffic.
The Blanchette Bridge on I-70 near St. Louis will be under construction during several summer weekends and for 12 months starting in November. MODOT suggests commercial vehicle drivers take a detour that will add five miles but cut down travel time.
For 12 months starting in November and for several weekends this summer, construction on Interstate 70's Blanchette Bridge over the Missouri River, between St. Louis and St. Charles, Mo., at mile marker 230, will detour westbound I-70 traffic.
Due to the construction, commercial motor vehicle drivers are urged to take a detour, using I-270 and Mo. 370 as an alternate route.
Between now and November, smaller weekend projects will close multiple lanes of I-70 near the bridge. These weekends, the the Missouri Department of Transportation says, are a good opportunity for drivers to get used to the detour route. Although the detour adds five miles to the route, it is expected to shave several minutes off of travel time compared to driving through the narrow work zones.
That work is scheduled for the weekends of June 22-24, June 29-July 1 and July 21-23. The dates are subject to change due to weather or supply issues.
The weekend of July 13-25 on the east end of the bridge, two lanes of I-70 will close in each direction as crews build crossover lanes in the median. In early November, the crossover will be put to use as the current westbound bridge is closed.
