The Missouri Department of Transportation reopened westbound Interstate 44 in St. Louis County ahead of Thursday evening rush hour; the eastbound lanes were reopened by 9 p.m. Thursday. The westbound exits at Soccer Park and 141 will remain closed.
More than 220 roads remain closed across the state, MoDOT said.
Interstate 44 had been closed between I-270 and Route 100 in Gray Summit for several days. Floodwaters from the Meramec River threatened parts of the highway. Manchester road (100) has been handling detour traffic while I-44 is closed. Route 47 in Warren County closed overnight. That puts a lot of traffic from Franklin and Warren Counties to St. Louis onto Route 100. The volume of traffic on the highway has dramatically increased. There was a 2.5 hour delay this morning. MoDOT says that the road is taking a beating.
In the Fenton, area Routes 21 and 30 at the Meramec were still closed. The main way in and out of town is Bowles. 141 at Romaine reopened to traffic Thursday morning.
All lanes of southbound Interstate 55 in Arnold are open to traffic between St. Louis and Jefferson counties. The Meramec River crested early Thursday morning and crews began opening lanes as the water receded. The Meramec Bottom ramp to southbound I-55 remains closed due to water on that ramp.
The St. Louis County Office of Emergency Management said Route 109 reopened.
