St. Louis city officials say the new viaduct that will carry Grand Blvd. over the railroad tracks in Midtown won't open to limited travel until the middle of June.
Crews had been hoping to open one lane of traffic in each direction by mid-May, says city Board of Public Service president Rich Bradley. But construction crews encountered poor soil conditions and a water line when they began digging.
"You dig in the ground in the Mill Creek Valley there, you can find just about anything," Bradley said.
