The Missouri Department of Transportation has canceled some lane closures on the Poplar Street Bridge this weekend.

All lanes on the Poplar Street Bridge will be open this weekend, though the department will still close the I-55 northbound exit ramp from 11 p.m. Saturday until noon Sunday. 

Some of the work can't be done in the predicted rainy weather, says MoDOT spokeswoman Kara Price, though she says crews may also have taken into consideration the numerous events at downtown venues this weekend.

The Delmar Blvd. bridge over Interstate 170 will be closed until it is replaced, the Missouri Department of Transportation announced today.
