(KMOV) -- Demolition crews expect to have the Interstate 270 overpass over Dorsett Road torn down by tomorrow's rush hour, but you can still expect some problems.
Tomorrow will be the first morning rush hour with the new, temporary bridge that will carry southbound traffic on 270. There's both a lane shift and narrow lanes at the work zone, so the speed limit is being lowered.
All of these changes are part of a complete redesign of the interchange in Maryland Heights.
