ST. LOUIS (KMOX) –All that rain St. Louis received this weekend had to go somewhere and now the backwash into sewer lines is to blame for a traffic nightmare shaping up on Interstate 70, that could last for days.
MoDOT engineer Deanna Venker says so much water entered the system that it collapsed eastbound lanes of the highway, early Sunday, in North St. Louis. “Hydrostatic pressure built up in the system, blowing the sewer line,” Venker explained. “That caused the pavement above to break-up and buckle.”
Venker says the two right-hand lanes of eastbound I-70 are closed between Shreve and West Florissant, and could remain closed all week, while MSD repairs the sewer line and MoDOT engineers replace the pavement. More than 40,000 motorists pass through that area every day. She suggests commuters planning ahead for traffic congestion there, or taking a detour.
